With 1,196 units sold, it’s a proven favorite among makers.
Why This Connector is a Must-Have
Perfect Fit for Standard Bowden Setups
Designed specifically for 2.5x4mm PTFE tubes, this pneumatic connector (PC4-M6 / PC4-01 style) fits perfectly into most filament dryer boxes, dry boxes, and direct drive extruder upgrades. The precise engineering guarantees a tight seal without the need for tape or glue.
Secure Locking Nut Included
Unlike basic push-fittings that can pop off under vibration or pressure, this kit includes a locking nut. Once tightened, it provides a rock-solid mechanical lock on your dryer box wall or enclosure panel. This prevents air leaks that ruin hygroscopic filaments like PLA, ABS, PETG, TPU, and Nylon.
Durable Nickel-Plated Brass Construction
Built to withstand the heat and mechanical stress of 3D printing environments. The nickel-plated brass body resists corrosion and thread stripping, while the stainless steel gripping collet holds the PTFE tube firmly without damaging it. The internal O-ring ensures a true pneumatic seal.
Easy Installation – No Tools Required for Tube
Simply drill a 6mm-7mm hole in your dryer box, insert the connector body, tighten the nut from the inside, and push your PTFE tube in until it seats. To release, just push the collet ring down and pull the tube out. It makes swapping filaments or maintaining your dry box incredibly fast.
