Parker 62NFBH-4 Compression Bulkhead Union 1/4 Inch Brass

Product Description

The PARKER 62NFBH-4 is a brass compression tube bulkhead union designed to create a secure, leak-resistant tube connection through a panel or bulkhead wall. It features compression fittings on both ends, allowing it to connect 1/4-inch outside diameter tubing on each side without the need for flaring or soldering. Rated to 150 psi maximum working pressure and capable of handling temperatures from -40 degrees F to 200 degrees F, this fitting is built for demanding fluid and pneumatic line applications. It meets D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards, making it appropriate for use in regulated plumbing, automotive brake, and fuel line systems.

This bulkhead union is suited for installations where tubing must pass through a panel, firewall, frame rail, or enclosure wall and terminate with a compression connection on each side. Typical applications include mobile equipment hydraulic lines, brake system tubing, refrigeration and HVAC copper tubing runs, and industrial fluid transfer systems. Plumbers, HVAC technicians, and mobile equipment mechanics working with 1/4-inch compression tubing will find this fitting appropriate for both new installations and repair work.

• Rated to 150 psi maximum working pressure
• Wide operating temperature range: -40 degrees F to 200 degrees F
• Complies with D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards
• Bulkhead design routes tubing cleanly through panels or enclosure walls

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 1/4-inch outside diameter compression tubing, including brake, fuel, and fluid transfer lines meeting D.O.T. and SAE standards.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified mechanics working on fluid or pneumatic systems. Depressurize and drain the line completely before removing or installing any compression fitting. Ensure the tubing end is cut square and free of burrs before seating it into the compression nut to achieve a proper seal. Tighten compression fittings to hand-tight plus the appropriate fraction of a turn per the fitting manufacturer guidance — do not over-tighten, as this can deform the ferrule and cause leaks.
