Parker 62HDBH-4 Compression Bulkhead Union 1/4 in Brass

Product Description

The PARKER 62HDBH-4 is a brass compression tube bulkhead union designed to create a secure, leak-resistant connection where a tube must pass through a panel, bulkhead, or enclosure wall. It accepts compression fittings on both ends and is rated for a maximum working pressure of 2100 psi, making it suitable for demanding fluid and pneumatic system applications. The 1/4 inch outside diameter tube size is a common specification in refrigeration, instrumentation, and compressed air circuits. Plumbers, HVAC technicians, and instrumentation professionals install this fitting when routing tubing through equipment cabinets or mounting plates.

This bulkhead union is used in residential and commercial applications wherever a tube line must transition cleanly through a partition. Typical install scenarios include refrigeration equipment panels, compressed air distribution assemblies, hydraulic enclosures, and instrumentation manifolds. Its compression-by-compression end connections allow for tool-assisted hand tightening without the need for soldering, brazing, or threading, reducing installation time in tight or confined spaces.

Key Features

• Compression x compression end connections on both sides of the bulkhead interface
• Brass construction offers corrosion resistance in fluid and pneumatic service environments
• Rated to 2100 psi maximum working pressure for high-pressure system compatibility
• Accepts 1/4 inch outside diameter tubing on both ends
• Bulkhead design mounts through a panel to route tubing across a wall or enclosure

Compatibility

Designed as an OEM-style replacement or direct installation fitting for systems using 1/4 inch OD compression tube connections routed through a bulkhead or panel wall.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or instrumentation technician. Shut off system pressure and depressurize the line completely before removing or installing any compression fitting. Use a properly sized wrench to tighten the compression nut while holding the fitting body stationary to avoid stressing the panel or bulkhead. Verify all connections are leak-free under pressure before returning the system to service.
