At Perfect Engineers, we offer industrial-grade Bulkhead Unions under our flagship brand PE-LOCK, designed specifically for secure tube-to-tube connections through panels, walls, or enclosures. Engineered with precision and durability, our bulkhead fittings ensure a strong, leak-proof seal in both high-pressure and corrosive environments.
Ideal for instrumentation panels, skid systems, tank installations, and process enclosures, PE-LOCK Bulkhead Unions deliver the safety, consistency, and long service life expected by global EPC contractors, OEMs, and process engineers.
A Bulkhead Union is a tube fitting used to connect two tubes through a wall or panel. It provides a robust, threaded-body design with nuts and ferrules on both sides, offering a pressure-tight connection across a fixed barrier.
This fitting is perfect when tubing must be passed through control panels, enclosures, or walls while maintaining system integrity and ease of disassembly.
