PG & PGE Series Pneumatic Push-in Union Fittings

Flexible Tube Connections for Pneumatic Layouts

The PG and PGE Series push-in fittings are designed for pneumatic systems where tube connections need to accommodate different routing requirements. Their union structures help keep air lines organized while the push-in connection reduces assembly time and simplifies later maintenance.

Shared Features for Efficient Installation

Both series incorporate practical details for compact pneumatic piping:

● Quick installation with a space-saving construction

● Tube direction can be adjusted after installation

● Ellipse-shaped release ring for convenient disconnection

● Taper threads pre-coated with Teflon for reliable sealing

● Internal hexagonal holes for installation in confined spaces

Two Configurations for Different Tube Arrangements

The main distinction between these pneumatic union fittings is their connection geometry:

● PG Series – Unequal Union Straight: provides a straight union connection with an unequal configuration, suitable when the connected tubing requires different connection dimensions.

● PGE Series – Diff. Diam Union Tee: provides a three-way union connection designed for different-diameter tubing arrangements.

Applications and Assembly

These fittings can be used in pneumatic automation, packaging machinery, assembly equipment, control systems, and compressed-air distribution circuits. Their compact construction is particularly useful where tubing connections need to fit within limited machine space.

For installation, cut the pneumatic tube cleanly and insert it fully into the selected port. Check that the tube is securely retained before pressurizing the system. The release ring allows quick removal during servicing, while the internal hexagonal hole assists tightening where access is restricted.
