Route an air line to a threaded port.
PC4-M5 Straight Pneumatic Fitting - 4mm Tube, M5 x 0.8 connects compatible 4 mm outside-diameter pneumatic tubing to a matching female-threaded equipment port. The straight layout suits compatible valves, air preparation equipment and general automation air lines.
One fitting, one selected model
Each base sales unit contains one complete PC4-M5 fitting. Release ring, gripping collet and supplied seals are part of the assembled fitting, not extra loose pieces. Tubing, equipment, thread sealant and installation tools are excluded.
Use tubing outside diameter to select the push-in end. Check the actual mating thread profile and installation clearance before ordering; nominal inch size alone does not establish compatibility.

Connect, check, then operate.
Isolate the air supply and fully depressurize the line. Confirm tubing material and operating conditions suit the installation. Cut the tubing square and remove debris. Tighten the threaded connection at the brass hex using a suitable method for the mating port; do not use the release ring as a wrench point.
Push the tube fully into the connection and gently pull back to check retention. Restore air gradually and check the joint for leakage. To remove tubing, depressurize first, press the release ring evenly, then withdraw the tube. No unverified insertion depth, tightening torque or pressure rating is implied.
