Need Extruder PTFE tube

My PTFE tube from extruder to hot end was cut too short and I need a new tube, I have the olives and swivel nuts that come in the package on prusa's site, but if there is a way to avoid the $15 just to ship the $2 part to the US, I would like to do that. In case it might be important, I do still have the small spare piece of PTFE that came with my printer.

I have equipped my printers with these PTFE's: https://www.captubes.com/

4/2 is a standard size and available almost everywhere. I would not recommend other materials, e.g. PVC or PU.

I'm more than sure that you can find PTFE tube closer to you.. just search for PTFE tube with outer diameter of 4mm and inner diameter of 2mm (for 1.75mm filament).

RE: Need Extruder PTFE tube

@jonah_mweather

is that for the short tube or the bowden? 
the proper size is 2mm for all mini pipes. 

the short hot end liner should be ok at 1.9mm

 

the bowden may be a bit tight especially where it goes through the olives

Penny Parts for your thoughts...

This is why I recommend ordering spare parts when ordering anything from Prusa3D, you'll never know when something random happens - like a cat who likes to gnaw on cables and PTFE  tubes, or cat hair getting caught in a fan and destroying it. 

Order the following the next time you order anything:

1. Prusa i3 Mk3 Feet (4x - you'll thank me later, they work better than the Prusa Mini foam pads and fit in the extrusions nicely, you can cut the top off of one and glue it under the Z axis)

2. Spare Hotend PTFE Tube

3. Spare Bowden Tube Assembly

4. Spare fans (both of them)

5. Prusa Printer Rod Grease - it's pretty cheap and it'll keep you from replacing rods every 200-400 hrs

All the above will cost far less to buy beforehand than frantically looking for spares at the last minute. There are plenty of suppliers who would gladly overnight you parts for a very large markup.
