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

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

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.

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.

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.

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

Due to my own silliness I have clogged the included teflon tube that comes with the Ender 5 Pro. I started looking online for replacements and saw these on Amazon. I decided to bite the bullet and give these a try. The fittings work with both the extruder and the supply motor well, make sure you do not over tighten them when putting them in. The tubes are long enough to easily reach the printing head from the filament drive, without being too long and needing to be clipped. If you have messed up your Ender 5 Pro filament tubes and fittings I would definitely recommend these as replacements. Its also nice to have them at hand when needed, so the pack of four makes it easy to print without fear of having to wait for a replacement.

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

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.

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