KEHIPI PC4-M6 & PC4-M10 Pneumatic Fittings Kit 20pcs 3D Printers Accessories

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.
