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

had to replace the bowden tube and fitting on my ender 3 pro. and this was highly recommended. it comes in a roll and you cut to length, the fitting fit perfectly and the tube has not given me any problems since installing it

Picked this up for my Ender 3 Max Neo. Everything works as expected.

The black PC4-M10 work well. The blue PC4-M6 have an internal crimp area that catches the filament that needed to be drilled out.

The PC4-M10 fittings have the 4.5mm inner diameter, not the bored out 6mm that other vendors seem to be shipping.I do wish they were packaged better than just being loose in a bag, but they all appear to have survived shipping.

These worked nice in my bowden e3d v6 3d printer heatsink with out issue. The old stock one started to lose it's grip on the PTFE tube I was using as I had some clogs in the hotted and needed to remove the tube. After a few times it started to lose it's grip and it was time to change it out for a new one. This one fit perfectly and grips the tube just like the OEM one did and been printing ever since.

I’m happy with these parts. The quality seems to be high. They fit very nicely in my extruder, no wobble and nice fit. The PTFE tube was very nice and seems well made.So far, I’m very happy!
