## Overview

The ALLEN TECH PTFE Teflon tubing is a 5ft long, 2mm inner diameter and 4mm outer diameter tube designed specifically for 1.75mm filament Bowden 3D printers. Crafted from high-grade PTFE, it offers exceptional chemical resistance, ultra-wide temperature tolerance (-454°F to 500°F), and UL-224 VW-1 flame certification. Its FDA-compliant materials ensure safety for food-contact applications, while its low friction and precise dimensions guarantee smooth, jam-free filament feeding, making it a trusted choice for professionals demanding reliability and performance.

## 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.

## Questions & Answers

**Q: what size should i pick if im using flashforge creator pro?**
A: If you're building a dry box you want the 2 mm inner diameter to best fit the 1.75 mm filament.  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

### ⭐⭐⭐⭐⭐ Review
*by N***. on 26 September 2020*

I used this 4mm OD 2mm ID tube to replace the insert in my 2010 Chicago electric 151 mig welder. It works great. They don't sell the replacement inserts for this old welder anymore.
