Question
Alex Zarenin –
Would these work with micro swiss hot end?

Tim Hoogland –
Only if it has the screw in type fitting. If you have the integrated fitting then it will not work with the microswiss.

Question
Josh (verified owner) –
Do these require a printed clip to lock them? The ones I received seem to release when the tube is push down

Tim Hoogland –
They do not. Your tubing should not be able to be pushed down if it is fully inserted. Fittings require tension on one end to keep it locked in place. Try inserting the tube all the way with the fitting backed out about 1/4 turn. Then once it is fully inserted tighten the fitting down the rest of the way.

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.
