Short answer: the 600 mm tube for the Moore 1 Series is $27.99 under SKU CXY11.0004, and the 700 mm tube for the Moore 2 Series is $28.99 under SKU CXY11.0026. Both are the same transparent PU tube at ID 6.5 mm and OD 10 mm, with the same tool-free quick-connect fitting. The length difference is the machine's feed path: the listing asks you to choose the right size for your printer, and a tube bought for the wrong series does not seat on the routing it was not cut for.

The honest note before the tables: the tube is designed for the Moore Series Clay 3D Printers, and other machines may not fit. The seller has not published the quick-connect fitting caliber, the thread specification, the tube wall thickness, or the maximum working pressure, so those fit details are merchant-confirmation items with store support before a cross-machine purchase. The machine context behind the tubes is the Moore 1 itself: an all-in-one clay printer on OSG dual-axis guide rails, driven by an electric push rod and screw extrusion with no air compressor, across eight languages — a screw-fed system that pushes clay through this line.

This guide keeps the two lengths beside each other on the same questions: which printer each fits, what the ID and OD numbers mean, how PU compares with PTFE, how the quick-connect fitting operates, how the line unclogs, and how a spare tube should be stored. All Tronxy pricing figures are fixed store prices on the QIDI Tech listing; competitor and ecosystem material notes are labeled as general practice or machine context, because material pricing and practice change by brand and region.

The scope of this guide is the feed line itself. It does not cover the barrel body, the extruder head, or a full continuous-feed system. General clay rules apply to every tube: watch the column through the transparent wall, unplug at the collar when the line stalls, and wash the tube in warm water with mild soap between sessions. A clay feed tube at ID 6.5 mm is a wide bore compared with a filament PTFE guide in the 1.75 mm class; that size gap decides everything about how the line is made, washed and unclogged.

Before the tables, the eight comparison questions used through this article. Each narrows the choice for a specific buyer: a Moore 1 owner, a Moore 2 owner, a classroom, a studio, a maker comparing materials, or a buyer troubleshooting a clogged line.

1. Which printer does each length fit? The 600 mm version is the feed line for the Moore 1 Series, at $27.99 under SKU CXY11.0004. The 700 mm version is the feed line for the Moore 2 Series, at $28.99 under SKU CXY11.0026. The listing's own guidance is to choose the right size for your printer.

2. What do ID and OD mean? The tube is specified at ID 6.5 mm and OD 10 mm: 6.5 mm inner diameter for the clay bore, and 10 mm outer diameter where the quick-connect fitting seats. The inner diameter carries the clay column; the outer diameter decides the fitting.

3. Material and wall: the tube is PU material, transparent, described as tough, flexible and durable with good clay performance. PTFE is the smooth, non-stick wall used in some continuous-feed ecosystems; the comparison below separates the two materials on flexibility, transparency and washability.

4. Connection operation: the listing states the quick-connect fitting joins the feeding tube easily, without special tools or skills. General clay-community practice for similar quick-connect fittings presses the collar to release the tube and pushes it back in until it seats.

5. Unclog routine: the community-proven unclog routine runs unplug the feed tube, extrude some clay out, clean the extruder head, and resume printing. The collar press turns the unplug step into a one-handed operation, and the transparent wall shows the column before you disconnect.

6. Cleaning and storage: rinse the PU tube in warm water with mild soap, let it dry, and store it flat or on the shelf. A spare tube swaps in while the used one washes; a dirty or damaged line ends the session faster than a clogged head.

7. Wear and replacement: a tube that cracks near the collar, hardens at the bend, or no longer seals at the fitting reaches replacement. The exact wear point is a merchant-confirmation item; the observable signs are the practical guide.

8. Cross-machine fit: the tube is designed for the Moore Series, with other machines possibly not fitting. Heated or pressure ratings are not published, so cross-machine buyers confirm with QIDI store support before purchase.

The Tronxy feed tube lists at two fixed prices on the QIDI Tech listing. The table below prices each version, lists the SKU and the printer series it covers, and matches the length to the buyer type. All figures are product facts from the listing; the buyer-type matching is working practice.

The length table reads as one slope: the 600 mm line covers the Moore 1 feed path at $27.99, the 700 mm line covers the Moore 2 feed path at $28.99, and the material, sizing and fitting operation are identical. The one-dollar price gap follows the longer cut of material, not a different product. A Moore 1 owner who buys the 700 mm version has extra line with nowhere to route it; a Moore 2 owner who buys the 600 mm version cannot reach the barrel. The listing's own guidance is to choose the right size for your printer.

The table below compares PU and PTFE on the questions a clay buyer actually checks: wall behavior, transparency, flexibility, washability, and the ecosystem where each material is used. The Tronxy figures are product facts from the listing; the PTFE notes are general practice and ecosystem context, labeled as such.

The material table's standout row is transparency: the PU wall shows the clay column, so a bubble or a stalled run is visible before the head clogs. The second decisive row is the ecosystem note: a filament PTFE guide in the 1.75 mm class is a tiny lumen for solid plastic, not a clay feed line at ID 6.5 mm. A buyer who chooses a tube by material name alone may own a rigid line that will not bend around the machine; a buyer who matches the PU tube to the Moore Series path gets a flexible wall, a visible column and a collar-press unclog.

The Tronxy tube is specified at ID 6.5 mm and OD 10 mm. The table below places those numbers against the tubing sizes a buyer might compare against, with the contrast labeled as general practice and ecosystem context. The point of the chart is to show the wide-bore reality of a clay feed line, not to recommend a replacement.

The sizing chart makes the bore reality visible: the Tronxy tube carries wet clay through a 6.5 mm inner diameter, while a filament PTFE guide in the 1.75 mm class guides solid plastic through a tiny lumen. The size gap decides everything about how the line is made, washed and unclogged. A Moore Series owner who replaces the line should buy the documented 600 mm or 700 mm tube rather than a generic roll cut to a guessed bore.

The tube price covers the PU line itself. The table below separates what the purchase includes from what the buyer supplies separately, and compares the adjacent material classes on the same cost lines. Competitor and ecosystem bands are general estimates without fixed dollar figures because pricing varies by brand and region.

The fair comparison is length-matched, not sticker-first. A Moore 1 owner who buys the wrong length has extra line with nowhere to route it; a Moore 2 owner who buys the 600 mm version cannot reach the barrel; a PTFE alternative assumes the ecosystem's fitting family; a generic roll forces a guessed bore; a threaded metal tube needs tools mid-run. The Tronxy price hides no motor-side or air-side equipment; the honest math is matching the printer series, buying the collar-press line, and keeping one spare on the shelf.

The 600 mm version of the Tronxy feed tube is the feed line for the Moore 1 Series, sold at $27.99 under SKU CXY11.0004. It is the same transparent PU tube at ID 6.5 mm and OD 10 mm, with the same tool-free quick-connect fitting, cut to the shorter feed path the Moore 1 routing requires. The listing asks you to choose the right size for your printer, and the 600 mm cut is that choice for a Moore 1.

The machine context behind the shorter cut is the Moore 1 itself: an all-in-one clay printer on OSG dual-axis guide rails, driven by an electric push rod and screw extrusion with no air compressor, across eight languages. The strength of this profile is a matched short line with no extra material to route: the PU tube bends around the Moore 1 path, the transparent wall shows the column, and a spare tube swaps in while the used one washes. The limit is that the 600 mm cut does not cover the longer Moore 2 routing; a Moore 2 owner who buys the 600 mm version cannot reach the barrel.

The 700 mm version of the Tronxy feed tube is the feed line for the Moore 2 Series, sold at $28.99 under SKU CXY11.0026. It is the same transparent PU tube at ID 6.5 mm and OD 10 mm, with the same tool-free quick-connect fitting, cut to the longer feed path the Moore 2 routing requires. The one-dollar price gap follows the longer cut of material, not a different product.

The strength of this profile is a matched longer line for the larger frame: the PU tube reaches the barrel on the Moore 2 path, the transparent wall shows the clay column, and the collar-press unclog works the same way. The limit is that the 700 mm cut does not shorten to the Moore 1 routing; a Moore 1 owner who buys the 700 mm version has extra line with nowhere to route it.

PTFE tubing is the smooth, non-stick wall used in some continuous-feed clay-printer ecosystems, where the line runs from a continuous-feed system through a machine-specific fitting family. It is a different material family than the Tronxy PU tube: less flexible, less transparent, and built around the ecosystem's own fitting rather than the Moore quick-connect collar.

The strength is a smooth wall that flushes easily. The weakness is the ecosystem assumption: the PTFE line matches a machine-specific fitting, and the Moore Series path has its own collar operation. A machine that ships with a PTFE feed path keeps its ecosystem line; a Moore Series owner reaches for the matched PU tube for the documented 600 mm or 700 mm cut.

Generic PU or PTFE tubing is the bulk-roll DIY line: buy a meter, cut it to length, and choose a fitting at the roll end. The DIY route works when the builder knows the machine's exact routing, bore and fitting spec, and fails when the bore is a guess rather than a match.

The strength is a low per-meter material cost. The weakness is that the cut length and fitting are on the builder: bore varies by stock, the push-fit or compression fitting is bought separately, and the Moore-specific 600 mm or 700 mm path is a guess. A DIY builder cuts bulk tubing to frame size; a Moore owner reaches for the matched quick-connect PU tube for a documented length.

A filament printer's PTFE guide in the 1.75 mm class is the tubing most makers already know: a tiny lumen that guides solid plastic through the print head. It appears in this comparison only to show the size difference, not to substitute one part for the other.

The strength is a cheap, familiar part on every FDM printer. The weakness as a clay feed line is the size: a 1.75 mm class guide cannot carry a 6.5 mm bore clay column, and a filament guide never washes wet clay through it. A mixed bench keeps the filament PTFE guide on the plastic printer and the PU tube on the clay bed.

The table below prices the two matched lengths across the purchase decision, computed from the listing prices. The per-length arithmetic is the SKU price itself; the buyer-type matching is working practice for the classroom, studio and home rotation.

The per-length decision table reads as one rule: match the SKU to the printer series. The 600 mm tube at $27.99 covers the Moore 1 path, the 700 mm tube at $28.99 covers the Moore 2 path, and the material, sizing and fitting operation are identical across the two. A mixed Moore fleet stocks one matched tube per machine plus one spare; a single-machine owner starts with the matched version and extends the rotation when the wash cycle backs up.

Branch 1 — You own a Moore 1 Clay 3D Printer. Buy the 600 mm version at $27.99 under SKU CXY11.0004. The PU tube bends around the Moore 1 routing, the transparent wall shows the column, and the collar-press unclog clears the line without tools.

Branch 2 — You own a Moore 2 Clay 3D Printer. Buy the 700 mm version at $28.99 under SKU CXY11.0026. The longer cut reaches the barrel on the Moore 2 path; the one-dollar price gap follows the longer cut of material, not a different product.

Branch 3 — You run a classroom with both printer series. Stock one matched tube per machine and one spare of each length. A clogged line swaps out between lessons while the used one washes; the wash cycle never blocks the bench.

Branch 4 — You are comparing PU against PTFE for a clay feed path. The PU wall is transparent, flexible and tough, with a visible column; the PTFE wall is a smooth non-stick surface in another ecosystem's fitting family. A mixed bench keeps the PTFE guide on the filament printer and the PU tube on the clay path.

Branch 5 — You are comparing a bulk roll against the matched tube. The bulk roll saves material cost but forces a guessed bore and a separate fitting; the matched tube buys the documented 600 mm or 700 mm line with the collar built in. A DIY builder cuts bulk roll; a Moore owner buys the matched version.

Branch 6 — You are unsure whether the tube fits your machine. Stop before checkout. The tube is designed for the Moore Series, and other machines may not fit. Ask QIDI store support with your machine details, because the fitting caliber, thread specification, wall thickness and maximum working pressure are merchant-confirmation items.

A school term, a studio rotation cycle and a home print cadence each wear lines on different schedules, but the length choice follows the same rule: match the SKU to the printer series, keep one spare on the shelf. The table below prices the recurring lines per scenario; actual counts depend on project size, clay body and session length.

The math after the length choice is deliberately simple: both versions run on warm water and mild soap, both unclog at the collar, and both store on the shelf. The budget difference appears when a guessed length cannot route, when a wrong ecosystem fitting stalls the class, or when a bulk roll forces a separate fitting. Match the SKU to the printer series, keep one spare, and the running cost stays predictable across a term or a studio cycle.

Connect the tube to the feed path: push the 600 mm or 700 mm PU line into the quick-connect fitting until it seats. The listing states the fitting joins the feeding tube easily, without special tools or skills; general clay-community practice presses the collar to release and pushes to seat. A well-seated fitting shows no gap at the collar.

Print and watch the column: run the first layer, and watch the clay move through the transparent wall. A bubble forming, a stalled column, or a color change in the line warns you before the head clogs. Clay moisture and consistency decide the feed: clay too soft slumps, clay too stiff stalls, and a body that sits too dry in the tube is the usual cause of a repeat clog.

Unplug, wash, store: when the line stalls, press the collar to release the tube, extrude some clay out, clean the extruder head, and resume printing. Rinse the PU tube in warm water with mild soap, let it dry, and store it on the shelf. A spare tube swaps in while the used one washes; a clean, seated, well-fed line lays the bead reliably.

For a Moore 1 owner replacing a worn line, a Moore 2 owner on the longer frame, a classroom outfitting both printer series, or a maker comparing PU against PTFE and bulk roll alternatives, the Tronxy Feed Tube Quick Connect for the Moore Series, sold through the QIDI Tech store at $27.99 for the 600 mm Moore 1 version and $28.99 for the 700 mm Moore 2 version, as a transparent PU line at ID 6.5 mm and OD 10 mm with a tool-free quick-connect fitting, is the practical feed-line choice in this guide: a transparent wall that shows the clay column, a collar-press unclog, and the documented length for each printer series.

PTFE alternatives remain another ecosystem's fitting family; generic bulk roll remains the DIY cut; filament PTFE guides remain the 1.75 mm class contrast. None of those alternatives should be stretched to replace the Tronxy quick-connect tube for the Moore Series feed path, and the PU tube should not be stretched into a production continuous-feed system.

The bottom line on the Tronxy feed tube: the 600 mm Moore 1 tube at $27.99 covers the shorter routing, the 700 mm Moore 2 tube at $28.99 covers the longer routing, both are the same transparent PU line at ID 6.5 mm and OD 10 mm with the same collar-press fitting, and PTFE alternatives, bulk rolls and filament guides belong to other ecosystems, which makes matching the documented length to your Moore printer the practical feed-line choice in 2026.
