Parker PT-00341 Steel Bulkhead Union 1-1/2 in Tube Od

Product Description

The PARKER PT-00341 is a steel flared tube bulkhead union designed to pass tubing through a panel, wall, or bulkhead while maintaining a secure, leak-resistant connection on both sides. It uses a 37-degree flare seat geometry with flare-by-flare end connections, conforming to the JIC standard widely used in hydraulic and fluid-power lines. The fitting handles a maximum working pressure of 3,000 psi, making it suitable for high-pressure hydraulic systems. The 1-1/2 inch tube outside diameter size is a common spec in industrial and mobile hydraulic plumbing. This fitting is installed by hydraulic technicians and pipefitters in equipment requiring a bulkhead-mounted tube pass-through.

This fitting is used wherever a tube line must pass through a structural member or panel and be secured in place. Typical applications include hydraulic power units, mobile equipment, industrial machinery, and fluid-power distribution panels. The flare-by-flare connection style allows both sides of the bulkhead to be connected and torqued independently, supporting clean routing on each face of the panel. The steel construction is appropriate for petroleum-based hydraulic fluids and many industrial fluid systems operating at elevated pressures.

Key Features

• 37-degree JIC flare seat on both ends for a metal-to-metal seal
• Flare x flare end connections for independent make-up on each side of the bulkhead
• 3,000 psi maximum working pressure rating
• 1-1/2 inch tube outside diameter sizing
• Steel construction for durability in high-pressure hydraulic service

Compatibility

Designed as a direct-fit bulkhead union for 1-1/2 inch OD tubing with 37-degree JIC flare ends in hydraulic and fluid-power plumbing assemblies.

Installation Notes

Installation is typically performed by a qualified hydraulic technician or pipefitter. Depressurize and drain the hydraulic system fully before removing or installing any fittings. Inspect flare seats on both the fitting and the tube ends for nicks or deformation before assembly, as surface damage will cause leaks under pressure. Follow the fitting manufacturer and system designer specifications for proper assembly procedure and tube preparation.
