The tube connection is sized for 1/8" outside-diameter tubing. Match the actual tubing OD, not its nominal internal diameter.

It turns the 1/8" pneumatic tube away from the threaded component where a straight connection would create an awkward bend or clearance problem.

Yes. The swivel form allows the tube outlet to be directed to the desired position during installation, rather than twisting the tubing to reach the connection.

The fitting uses a 1/8 NPT male pipe thread. Select the matching NPT female port and an appropriate thread seal; do not treat it as a BSPP parallel thread.

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.
