Parker 72338239 Push-to-connect Union 1/4 Inch Od

Product Description

The PARKER 72338239 is a push-to-connect union tube fitting designed for quick, tool-free connections in pneumatic and fluid-handling lines. Constructed from bio-sourced Nylon 11, the body offers strong chemical resistance and durability in moderate-pressure applications. The fitting is rated to 230 psi and accepts tubing with a 1/4 inch outside diameter on both ends, making it a straight inline union for joining two runs of equal-size tubing. EPDM o-rings provide a reliable seal against water, steam, and many common industrial fluids. This fitting is sold in a package quantity of 10 and is commonly installed by HVAC technicians, plumbers, and industrial maintenance professionals working on pneumatic controls, water lines, or process tubing systems.

This fitting is suited for residential and light commercial applications where fast assembly and disassembly are priorities. It is commonly used in pneumatic control lines, water distribution sub-systems, and equipment plumbing where 1/4 inch OD tubing is the standard. The push-to-connect mechanism allows for rapid field installation without thread sealant, flaring tools, or compression sleeves. Each unit ships in a package of 10, making it practical for service vans and multi-connection jobs.

Compatibility

Designed as an OEM-style push-to-connect union for systems using 1/4 inch outside diameter tubing in pneumatic controls, water distribution, and light industrial fluid-handling applications.

Installation Notes

Installation is performed by HVAC technicians, plumbers, or industrial maintenance personnel. Before servicing any line, depressurize the system completely and shut off the fluid or air supply. Verify that tubing ends are cut cleanly and squarely with a tube cutter for a proper seal; ragged or angled cuts are a common cause of push-fit leaks. After insertion, perform a pressure test at working pressure before returning the system to service.
