The tube connection is sized for 1/4" outside-diameter tubing. Match the actual tubing OD, not its nominal internal diameter.

This PCF model provides a female threaded connection; the mating pneumatic component needs the corresponding male thread.

Use a female stud for a male threaded component; use the male stud for an internally threaded port.

PCF1/4-N2 has a female 1/4 NPT connection. Match it to the corresponding male-threaded component; the push-to-connect side accepts 1/4" tubing.

The P-Series fitting family is described for industrial compressed-air and vacuum service. Confirm that the tubing, O-rings and pressure or vacuum conditions are appropriate for the complete system.

Isolate pressure or vacuum first. Depress the release collar fully and pull the tube straight out. The Click-Click feel and sound are associated with depressing the collar during tube release, not with inserting the tube. Cut the tube end square before reconnecting.

The fitting body is nickel-plated brass, with the sealing and gripping components stated in the technical specification table.

No potable-water approval is stated for this P-Series fitting. Use a product with documentation explicitly covering the required drinking-water standards rather than assuming pneumatic fittings are certified.
