The tube connection is sized for 5/16" outside-diameter tubing. Match the actual tubing OD, not its nominal internal diameter.

It turns the 5/16" pneumatic tube away from the threaded component where a straight connection would create an awkward bend or clearance problem.

The extended body creates additional stand-off clearance at the port, which can help route tubing past adjacent fittings or a nearby machine panel.

This 1/4 male universal thread is designed for the matching-size flat-faced female NPT, BSPT or BSPP port. Confirm the port has the required flat sealing face and install according to the fitting instructions.

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 acetal engineering polymer (POM), with the separate gripping, sealing and any threaded components identified in the 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.
