Parker 62CBH-4 Compression Tube Bulkhead Union 7/16-24

Product Description

The PARKER 62CBH-4 is a brass compression tube bulkhead union designed to route tubing through a panel, bulkhead, or partition wall while maintaining a secure, leak-resistant connection on both sides. It features compression fittings on each end, allowing tubing to be connected without flare preparation or threading. The fitting carries a maximum working pressure of 300 psi and is rated for temperatures ranging from -65 degrees F to 250 degrees F. It conforms to SAE J-512 standards, making it appropriate for hydraulic, pneumatic, and fluid transfer applications where a reliable through-panel seal is required. Licensed plumbers, pipefitters, and HVAC technicians regularly install this type of fitting in equipment panels and enclosures.

This bulkhead union is suited for residential and light commercial applications where tubing must pass cleanly through a structural panel or equipment enclosure. It is commonly used in refrigeration systems, fuel lines, hydraulic assemblies, and instrumentation tubing runs. The compression-by-compression end connections simplify installation in tight spaces where a wrench can be applied to both sides of the panel. The brass construction provides corrosion resistance appropriate for a wide range of compatible fluid media.

Compatibility

Designed as an OEM-style replacement or service fitting for compression tube bulkhead union applications conforming to SAE J-512 with a 7/16-24 thread size.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or qualified HVAC technician. Depressurize and isolate the system fully before removing or installing any compression fitting. Hand-tighten the compression nuts first, then apply a controlled wrench turn to seat the ferrule without over-tightening, which can crack the ferrule or distort the tubing. Verify system pressure does not exceed the 300 psi rated working pressure after returning the system to service.
