Fits my ender 3 v2 and holds the bowden tube better than the original brass one. No movement on retractions. It has about 10 teeth that hold the tube rather than the 4 on the original connector.

great

Great pull/pull fitting for the 4mm ptfe tubing used for 1.75mm filament. Minimal shifting of tube on retractions and linear advance moves. Tip; to completely eliminate shifting tubes in any fitting, strap a zip tie between the fitting and the plastic push/pull ring. This will keep the tube in place solidly.

These fittings are one of those "Oh yeah; now that's better" kind of change overs. Right away you can feel how much better constructed these are than the brass factory originals. The mechanism has a far stronger spring back, yet they are easier to apply and release. The original was never this good to begin with. I bought several, as I didn't enjoy the down time I had from the original failing after two years of barely any use. I mean less than 50 hours. That made me think these fittings are treated as consumables, but I can't imagine this better type breaking down any time soon.

works well put this thing together pretty well

It's great to have 3DPrintingCanada near by. They had parts in stock and packed for pickup same day.

Very happy with these couplers on my ender 3 pro! Actually grips your ptfe tubing and can be removed easily! A lot better then the stock ones from reality! Must buy for anyone with and ender 3!

3D Printing Canada you are great! Good prices, a very nice selection of product and a fast shipping. If could say one small downside that you sometime do is, using Purolator as shipper (they are the worst of all on every aspect and customer service is very bad) but you guys are awesome. Keep doing what you do, you're great. Love you guys, Thank you. Francois
