This is your normal, everyone needs and therefore everyone should have it PTFE tube. Will work for 1.75mm filaments and 4mm couplers.The internal diameter is a little larger to allow for more room for your filament.

This tube is great for ERCF!

Order these by the meter (e.g. quantity 2 = 2 meters)we can cut these however you wish though, so if you want special cuts of your tube please place a note when checking out.

Please note -because of how these are pulled, if you order more than 5 meters we may cut in 5 meter increments (e.g. if you order 9 meters we may cut a 5 meter and a 4 meter strip (with a small overage).
