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

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

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

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.

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

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

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

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

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

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.
