Installation Note: When installing these just install them finger tight, do not use a wrench or over tighten as you can crack the fitting.
- Metal grip inside
- Allows for PTFE to pass through
- Holds on to tubing strong
- Commonly Used on Extruder side
- CR-10
- CR-10S
- Ender 2/3/4/5
- Alfawise U10
- And more (see below)
- If using these with a “MK8” style extruder with a gap between the feed gear and the PTFE tube you will need to close that gap or your PTFE fitting will be damaged.

Fixed the extruder/bowden tube movement on my ender 3 max neo!

If you’re looking to replace the trash stock coupler on your CR-10 is this the way to go. Had an issue where the PTFE tube would slide around inside the coupler leading to filament oozing. After installing this new part, the tube stays in place and the filament retracts properly. Highly recommended.

I’ve gone through all those cheap pneumatic coupler out there, and they ALL tear apart the bowden tube. I’ve seen tubes prolapse themselves, causing choke points, i’ve had filament pierce the tubes where they connect at the coupler, I’ve seen it all. Those cheap ones don’t even release the tube when you depress the top.
But finally, i found a set that doesn’t do any of that but still grips hard. The difference is night and day. The price you pay here is well worth it. No more broken bowden tubes.
