KEHIPI PC4-M6 & PC4-M10 Fittings Kit

This 20-piece kit supplies PC4-M6 and PC4-M10 pneumatic push-to-connect fittings plus PTFE tubing for Bowden extruders on 1.75 mm filament printers. It suits makers who maintain or upgrade machines such as Ender 2, Ender 3, CR-10 or Monoprice Mini models and want a ready assortment of both thread sizes.

Thread M6 and M10 limits for 4 mm OD tubing

Both fitting types accept only tube with a 4.0 mm outside diameter and a 4 mm inner bore at the collet end. The M6 variants use a 6 mm thread while the M10 variants use a 10 mm thread, so each size fits only the matching threaded port on the hot-end or extruder body. The included 1.5 m PTFE tubes have a 2.0 mm inside diameter and 4.0 mm outside diameter.

Mixed copper and stainless steel construction

PC4-M6 fittings are made from copper and plastic, while PC4-M10 fittings use stainless steel and plastic for anti-oxidation and high hardness. This material split decides whether the kit matches the specific port metallurgy your printer requires.

商品問答

Should I choose the PC4-M6 or PC4-M10 fittings for my printer?

The kit includes 4 PC4-M6 fittings with 6 mm threads and 4 PC4-M10 fittings with 10 mm threads; both accept 4 mm OD Bowden tube. Select the thread size that matches your extruder and hot-end ports.

How does the 2.0 mm inner diameter of the PTFE tube affect 1.75 mm filament?

The 2.0 mm ID tube leaves a small clearance around 1.75 mm filament, reducing friction and helping consistent feeding through the Bowden path.

What does the push-to-connect interface mean for installation?

Push the 4 mm OD tube into the fitting until it seats; the internal collet grips automatically. To release, press the collet down and pull the tube out.
