PI Series Pneumatic Push-in Stem Fittings

Compact Stem Connections for Pneumatic Tubing

The PI Series push-in stem fittings provide a practical way to connect pneumatic tubes while keeping installation compact and accessible. Their stem configuration is suited to air circuits where flexible tube positioning and efficient use of installation space are important.

Design Details for Faster Pneumatic Assembly

These pneumatic push-in fittings combine several features to make tube installation and servicing easier:

● Quick push-in connection for simple assembly

● Compact structure for space-limited pneumatic layouts

● Tube direction can be adjusted after installation

● Ellipse-shaped release ring makes tube removal easier

● Pre-coated Teflon taper threads help provide reliable sealing

● Internal hexagonal holes simplify mounting in narrow locations

The PI Series Union Stem provides a standard union connection, while the Unequal Union Stem accommodates connection arrangements involving different tube sizes.

Where PI Series Fittings Are Used

PI Series fittings are suitable for pneumatic automation, machinery, control cabinets, air distribution circuits, and other equipment requiring compact tube connections. Their flexible routing makes them useful when piping space or connection orientation is restricted.

Installation: Push the tube fully into the fitting to establish the connection. Adjust its direction after installation if necessary. For removal, press the release ring while pulling the tube outward, then reconnect the tubing as required.
