Parker 62HDBH-2 Compression Bulkhead Union 1/8in Brass

Product Description

The PARKER 62HDBH-2 is a compression tube bulkhead union designed to route tubing through a panel, bulkhead, or enclosure wall while maintaining a secure, leak-resistant connection on both sides. Constructed from brass, it accepts compression fittings on both ends and is rated for a maximum working pressure of 4300 psi, making it suitable for demanding fluid and instrumentation systems. The 1/8 inch outside diameter tube size positions this fitting in light instrumentation, pneumatic, and hydraulic control line applications. Plumbers, HVAC technicians, and instrumentation specialists install this type of fitting where tubing must pass cleanly through a structural barrier.

This bulkhead union is suited for use in commercial and industrial applications where tubing lines must penetrate panels, enclosures, or machine walls. Typical installations include pneumatic control systems, refrigeration instrument lines, hydraulic circuits, and process instrumentation tubing runs. Its all-brass construction resists corrosion in environments where moisture or mild chemical exposure is a factor. The compression-by-compression end configuration allows connection to standard compression tubing on both the panel-interior and panel-exterior sides without soldering or flaring.

Key Features

• Brass construction for corrosion resistance in fluid and pneumatic systems
• Compression x compression end connections on both sides for tool-assisted, leak-resistant assembly
• Rated to 4300 psi maximum working pressure
• Designed to mount through a bulkhead or panel wall, routing 1/8 inch OD tubing cleanly between two sides
• No soldering or flaring required for installation

Compatibility

Designed as an OEM-style compression fitting for use with 1/8 inch outside diameter tubing in standard compression tube systems.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or instrumentation technician. Shut off all system pressure and depressurize the line before removing or installing any compression fitting. A correctly sized hole must be drilled or machined in the bulkhead panel to accept the fitting body, and the locknut must be tightened to the manufacturer specification using an appropriate wrench — do not over-tighten, as this can crack the brass ferrule or distort the fitting seat. Verify all joints are leak-free under system pressure before returning the line to service.
