Brass Bulkhead Union

The Brass Bulkhead Union is a precision-engineered two-piece fitting designed to create a reliable, leak-proof pipeline connection through a panel, tank wall, or bulkhead — while allowing the line to be easily broken and remade without disturbing either side of the installation. Manufactured from high-grade free-cutting brass, it combines the mechanical strength of a bulkhead mount with the convenience of a union joint, making it an ideal solution for systems that require regular maintenance or future modifications.

Key Features:

• High-Grade Brass Construction: Machined from premium free-cutting brass for outstanding corrosion resistance, dimensional precision, and long operational life across demanding industrial, marine, and hydraulic environments.
• Union Joint for Easy Disconnection: The built-in union coupling allows the pipeline to be separated at the bulkhead point in seconds, with no need to cut or reroute pipework during maintenance or system upgrades.
• Secure Panel Mounting: A robust locking nut clamps the fitting firmly through the panel or tank wall, ensuring it remains firmly seated under vibration, thermal cycling, and sustained operating pressure.
• Leak-Proof Sealing: Precision-machined thread profiles and accurately formed seating faces deliver a consistent, pressure-tight seal that resists leakage throughout its service life.
• Wide Thread and Size Range: Available in BSP, NPT, metric, and custom thread forms across a comprehensive range of pipe sizes to suit every international standard.

Applications:

• Hydraulic and Pneumatic Systems: Routes pressurised fluid or air lines through machine frames and enclosures while providing a reliable disconnect point for maintenance.
• Water Treatment and Tank Installations: Used on storage vessels and treatment tanks where inlet or outlet lines must pass through the vessel wall.
• Marine and Offshore Equipment: Applied in bulkhead penetrations on vessels and offshore structures where a reliable, serviceable pipe connection is essential.
• Fuel and Chemical Processing: Suitable for panel and bulkhead penetrations in fuel delivery systems and chemical plant installations.
