A lot of creators complain that these style PC4-M10 fittings come with wrong sized threads. I don't know. I do know that these things use NPT (pipe) threads - which have a taper. If you design a straight thread part, the taper of the fitting's thread will cause a mismatch. The likely cause of those complaints. Supposedly (I have not tested this) the PC4-M10 fittings use a 1/8"-NPT thread.

These are great. No C clip needed to hold the bowden tube in. Cheaper then the other leading brand

It grips as it should. Unlike the stock ones. Even by adding a small cable tie the stock doesn’t hold for long and you end up wasting your tubing. So this is a worthy purchase.

it worked out great!!!

Works as expected -has been in service for a couple of weeks and no issues so far. Replaced as part of "Luke's Fix" on the hot end.

FYI I did not buy this but I have worked at a pneumatic fluid power specialist for 20 years.... this item is NOT stainless steel. The body of the item is nickel plated brass, with a plastic collet and the “grab ring” Inside is stainless steel. Misleading to state fitting is stainless steel, actual stainless steel body pushin fittings would serve Zero purpose, but the fittings would cost between 5 to 10 times the price.... due to SS corrosion resistance. Which is not needed here.

10 time better than the Creality original.

Replaced my Bowden tube and fittings with parts from 3DPrintingCanada. No more slipping Bowden causing jams.

fits great

Solved my problem and was quick and easy to install.

Works great! Solid fitting I should have bought more!

It is a great upgrade from the original connector. It provides a positive lock on the bowden tube that will not back off!
