Parker 72338304 Bulkhead Union Push-to-connect 1/4 in Od

Product Description

The PARKER 72338304 is a push-to-connect bulkhead union tube fitting designed to join two tube runs through a panel or wall without additional tools. Rated to 230 psi and constructed from bio-sourced Nylon 11, this fitting accepts 1/4-inch OD tubing on both ends and seals with an EPDM o-ring. The white body is lightweight and corrosion-resistant, making it a practical choice for pneumatic, fluid transfer, and instrumentation lines where a panel passthrough is required. Plumbers, HVAC technicians, and instrumentation installers are the primary trades who use this fitting in both shop-fabricated and field-installed assemblies.

This bulkhead union is suited for residential and light commercial applications where 1/4-inch OD tubing must pass through a bulkhead, enclosure wall, or panel. Typical use cases include pneumatic control lines, condensate and drain tubing routed through equipment panels, and small-bore fluid lines in packaged equipment. The push-to-connect design allows fast hand-insertion of tubing without thread preparation or sealant. Each package contains 10 fittings, with a minimum order quantity of 1.

Key Features

• Push-to-connect design accepts 1/4-inch OD tubing on both ends for tool-free assembly
• Rated to 230 psi for use in pneumatic and low-pressure fluid lines
• Bio-sourced Nylon 11 body offers chemical resistance and reduced environmental impact versus petroleum-based polymers
• EPDM o-ring provides reliable sealing compatibility with water, steam, and many hydraulic fluids
• Bulkhead union configuration routes tubing through panels, enclosures, or walls with a secure, leak-resistant passthrough
• White color and lightweight construction simplify identification and handling in the field

Compatibility

Designed as an OEM-style push-to-connect bulkhead union for systems using 1/4-inch OD tubing in pneumatic or fluid transfer applications.

Installation Notes

Installation requires depressurizing and draining the line before inserting or removing tubing. Tubing should be cut cleanly and squarely and deburred before pushing fully into the fitting to ensure proper engagement of the internal collet. To release tubing, depress the collet ring while pulling the tube straight back. Follow applicable system pressure and fluid compatibility requirements before placing into service.
