Zeelo PC4-M6 Pneumatic Fitting Push to Connect + PC4-M10 Straight Quick in Fitting for 3D Printer Bowden Extruder (Pack of 20pcs)

Teeth failed on the inside, it chewed up my new Capricorn tubing.

Really inexpensive fix for replacing the ptfe tubing. Makes the job easy and quick. Don’t need them often but makes the job easy when you do

Its just a tube for Gods sake, why would you pay 4x for a Capricorn? It does not do the job any better. For $9, this will outlast the printer. Ive been printing 2 years, and first time the tube clogged, I just cut it shorter past the clog, but this time the clog was in the middle so I had to get new tubes. I kinda like the white tube better because I can see where the filament is when I am inserting it. This blue tube is opaque. Also, the tube is rolled like in the picture to fit a sandwich zip lock bag, so some of them kind of have a little crease or disformed, so you have to cut the tube you are going to use avoiding the part where it was bent too much. I highly recommend this.

Tubing is good size and fittings work great.

I bought these for my 3D filament dry boxes so I wouldnt have to open them to feed filament to my printer. They work great.

Works exactly as described, cut it to desired length. Using an Xvico X3 Pro 3d printer.

These worked perfectly for my Longer Pro and even better to come in a set to have spares on hand.

I have had multiple other brands break, but have not had an issue with these. So far so Good.

What more to say.

Good aftermarket replacement for ender 3. No issues with gold fittings but jury still out on silver ones. Quick release seems to bind and dig into bowden tube. Not sure if its a function of the connector or off brand Teflon tube. Look into YouTube videos on how to properly install these with your chosen bowden tube so that you minimize the possibility of leakage around tube and you will not have to remove this connector to clean extruder. Nice to only need 1 wrench now. BTW, I bought this pack as I have 10 ender 3s and 2 cr-10s so its overkill if you only have 1 printer.
