Push-fit Bowden coupler for 4 mm OD filament tube. This PC4-01 / PC4-M10 style pneumatic fitting grips PTFE or FEP tube with an internal collet so the tube stays seated through ext ruder and filament-path motion. Why use this fitting Fits the common 4 mm outer-diameter Bowden tube used with 1.75 mm filament paths. Threaded metal body installs into compatible hotends, extruders, filament sensors, buffers, and printed mounts that call for a PC4-01 or PC4-M10 style coupler. Push the tube in to lock it; press the collar down to release the tube for service. Specifications Part family: PC4-01 / PC4-M10 straight pneumatic push fitting Tube fit: 4 mm OD PTFE/FEP Bowden tube Filament context: typically used on 1.75 mm printer filament paths Available collar colors: black or blue Use it with Transparent FEP Tube for filament-feed runs. Collet Clip when you want extra retention at a push-fit connector. Extruder Collet ECAS04 if your printed part calls for an embedded collet instead of a threaded coupler. Gotchas Check the printed part or hotend thread before ordering. PC4-01 and PC4-M10 are commonly treated as interchangeable in printer BOMs, but strict pneumatic specs distinguish 1/8 NPT-style PC4-01 from metric M10 threads. This is the coupler only; tube, clips, and printed mounts are sold separately. Show more
