The model specifies 1/8" nominal connection size(s). Check the plug-in stem and compatible receiving fitting, rather than assuming every connection accepts loose tubing.

The plug-in end inserts into a compatible push-to-connect fitting; the remaining 1/8" tubing connection(s) route the pneumatic line. It does not screw into a pipe-threaded port.

Use a compatible receiving port sized for the plug-in stem, and check the tube outside diameter and retention method before pressurising the assembly.

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.
