Engineered to withstand extreme temperatures (-454°F to 500°F) and harsh chemical environments, it features UL flame certification and FDA-compliant materials, ensuring reliable, jam-free filament feeding and long-lasting performance in professional and industrial 3D printing setups. ## Description Allen Tech PTFE tubing is made of PTFE (Polytetrafluoroethylene),PTFE tubing can be used in extreme temperatures and in harsh chemical environments. It's chemically inert, has low permeability, and has the lowest friction coefficient of any tubing. Temperature range is -450 to 500°>F; melts at 620°>F. Allen Tech PTFE tubing is UL-recognized (Flame rating: UL-224 VW-1), Excellent resistant to acids, alkali and all kinds of organic solvents: ASTM D543, and Raw materials meet FDA requirements per FDA 21 CFR 177.1550 for use with food contact surfaces. Widely used in electronics, chemicals, medical and industrial Review: Works for me - Very thin but very low resistance for pulling filaments Review: I have a Prusa i3 MK3s with MMU2S multi-material upgrade. I replaced all of the existing 2mm inner-diameter PTFE tubing (from the spool rewinders to the MMU2S, and from the MMU2S to the extruder) with this 3mm inner-diameter tubing. Now the filament can move more freely through it, and if the end of a retracted filament happens to be somewhat swollen, it avoids the possibility of jamming inside the tubing. ## Features - ID:2mm(0.079'')/OD:4mm(0.158''),Length:5ft.Material: PTFE(common name:Teflon).For 1.75 filament Bowden 3D Printer,Translucent - Temperature range (Degree F):-454 to 500.

That's what I used when I built my dry box and it works great. If you're looking to replace the guide tubes that came with the printer, you'll need something wider, looks like mine is 8 mm outer diameter. **Q: Does this work with Ender 3 v2?** A: It should. **Q: Can this be used for siphoning wine?** A: Very probable but I would think a bigger diameter tube would be better, and a cheaper option would be polythene tubing. **Q: What about the replacement blades? Can I order more separately?** A: Sorry, we just sell tube cutter, blades are not sold separately ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works for me *by R***. on 27 December 2025* Very thin but very low resistance for pulling filaments ### ⭐⭐⭐⭐⭐ Review *by A***H on 10 February 2021* I have a Prusa i3 MK3s with MMU2S multi-material upgrade. I replaced all of the existing 2mm inner-diameter PTFE tubing (from the spool rewinders to the MMU2S, and from the MMU2S to the extruder) with this 3mm inner-diameter tubing.

It works great. They don't sell the replacement inserts for this old welder anymore. ## Frequently Bought Together - PTFE Teflon tubing 5ft- 2mm ID X 4mm OD for 1.75 Filament Bowden 3D Printer -Allen Tech PTFE Teflon Tube - BIQU PC4-M10 Pneumatic Connector Fittings Bowden Tube Coupler Male Straight PTFE Tube Push for E3D-V6 Bowden Extruder Compatible with Ender-3 Ender-3 V2 3D Printers (Pack of 10pcs) - SHKI 20 Pcs 608 2RS Ball Bearings – Bearing Steel and Double Rubber Sealed Miniature Deep Groove Ball Bearings (8mm x 22mm x 7mm) (608 2RS) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/367381626-ptfe-teflon-tubing-5ft-2mm-id-x-4mm-od-1](https://www.desertcart.hr/products/367381626-ptfe-teflon-tubing-5ft-2mm-id-x-4mm-od-1) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-17*
