Parker 62PTCBH-6 Brass Bulkhead Union 3/8 Inch Tube Od

Product Description

The PARKER 62PTCBH-6 is a brass push-to-connect bulkhead union designed for tube-to-tube connections through a panel or bulkhead wall. It accepts 3/8 inch outside diameter tubing and holds up to 250 psi, making it suitable for demanding pneumatic and fluid-line applications. The fitting uses a Buna-N O-ring seal for reliable leak resistance across a wide temperature range. Rated for DOT air brake service, it meets the requirements of mobile and commercial vehicle pneumatic systems. Licensed plumbers, HVAC technicians, and fleet maintenance professionals typically install this fitting in compressed-air, brake, and similar fluid-conveyance lines.

This bulkhead union is rated for DOT air brake applications and is well-suited to commercial vehicle air systems, industrial pneumatic lines, and equipment requiring a panel-mount tube pass-through. The push-to-connect design allows for fast, tool-free tube insertion while maintaining a secure, pressure-rated seal. It is appropriate for use in both mobile equipment and stationary compressed-air installations where a tube-to-tube bulkhead connection is required.

Compatibility

Designed as a DOT-rated push-to-connect bulkhead union for tube-to-tube applications using 3/8 inch OD tubing in compressed-air, air brake, and compatible pneumatic fluid-line systems.

Installation Notes

Depressurize and lock out the air or fluid system completely before removing or installing any fitting. Ensure tubing is cut cleanly and squarely, and that the tube OD matches the 3/8 inch fitting specification before insertion. Bulkhead installations should confirm proper panel thickness and mounting hardware torque per the equipment manufacturer's guidelines. This fitting is intended for installation by qualified technicians familiar with DOT air brake regulations and applicable pneumatic system codes.
