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

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.

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

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.

Tubing is good size and fittings work great.

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

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.

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

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.
