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

Worked as intended. Using on a Prusa MK3S with MMU2 Upgrade.

I use this with 1.75MM to get from my dry-box to printer. It works, but the resistance when pushing/pulling through is more than Id like. Im still using, and havent had any issues after putting about 1kg through it, but the resistance when loading filament through it does not make me confident. I would not use this for TPU from a dry box.

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

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.

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.

Heat resistant, about enough to make 12 Bowden tubes for the Ender 3 Pro

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.

This replacement tubing/fittings got my Anycibic Mega S printer back into action after one of the original fittings gave up the ghost & screwed up a print for me :-( . The parts fit onto the printer as they should & Ive done multiple prints since installing them. I would recommend these parts for good value & longevity of use.

Bought this to repair my printer after a malfunction. It works like a charm now.

The products shipped on time and fit perfectly. I would recommend this product to anyone that needs quality fittings at a great price.
