Parker 72338320 Bulkhead Union Fitting 1/2 Inch Od

Product Description

The PARKER 72338320 is a push-to-connect bulkhead union tube fitting designed for use in pneumatic and fluid transfer systems where a tube line must pass through a panel, bulkhead, or enclosure wall. Constructed from bio-sourced Nylon 11 with an EPDM O-ring seal, this fitting accepts 1/2 inch OD tubing on both sides and creates a secure, leak-resistant connection without tools. It is rated to 160 psi, making it suitable for a wide range of compressed air and low-pressure fluid applications. The white Nylon 11 body offers good chemical resistance and dimensional stability. Plumbers, HVAC technicians, and industrial pipe fitters install this type of fitting in panel-mounted plumbing and pneumatic control assemblies.

This bulkhead union is suited for residential and light commercial pneumatic systems, compressed air distribution, and fluid handling lines where tubing must route through a panel cutout or partition wall. The push-to-connect mechanism allows for quick assembly and disassembly, reducing installation time in tight or frequently serviced locations. Bio-Sourced Nylon 11 construction provides resistance to hydrocarbons, moisture, and common industrial fluids encountered in HVAC, pool, and plumbing service environments. No compatibility with specific system models or replacement part numbers was stated in the product data.

Compatibility

Designed as an OEM-style push-to-connect bulkhead union for systems using 1/2 inch OD tubing in pneumatic, compressed air, or low-pressure fluid applications.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or industrial pipe fitters familiar with push-to-connect pneumatic fittings. Before servicing, depressurize and isolate the line fully before inserting or removing tubing. Ensure the tube end is cut cleanly and squarely with no burrs or ovality before insertion to maintain a proper seal. Verify panel cutout dimensions match the fitting body before mounting to avoid housing stress or seal compromise.
