Aokin 10 Pcs PC4-M10 Pneumatic Fitting for Creality Ender 3/3 Pro/3 V2, Ender 5/5 Pro/5 Plus, CR-10/10S, etc

Great product!!

Got this to replenish my supply. They are a good quality at a good price.

worth it!

The PC4-M10 fittings have the 4.5mm inner diameter, not the bored out 6mm that other vendors seem to be shipping. This was important for my 3D printer setup.

I am using these as fittings for a y-splitter for my bambu labs ams and other spoolholder. Works great, holds onto ptfe without a problem. I was missing one fitting but I don’t mind much.

Fits on my Ender 3 pro v2, CR10 MAX, & CR10s. Works as oem replacement

Great set. Removed 1 star for not including the little clips too.

They fit and work properly but one broke within a week of usage. Hopefully the others will hold up longer.

Thank you for fast shipping, what I was looking for

If you have an Anet ET4 only half of these fittings will work for you. The blue PC4-M6 fit the feeder end where only the filamet needs to pass through the center. The black/hot end fitting will not fit. The outer diameter is correct but the inner diameter needs to accept the Bowden tube completely through the fitting. It needs a 4 mm ID. These will allow the filamet but not the tube itself, which must pass through and rest on the nozzle end. This is my 2nd attempt to find fittings for the Anet ET4 printer on Amazon. My rating is based on my error in judgement. For the appropriate printers, these may well be 5 stars.
