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.

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.
