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

What more to say.

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

Tubing is good size and fittings 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.

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

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.

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