#6 Bulkhead Flare Union

The #6 Bulkhead Flare Union is a precision-engineered fitting designed for serious marine plumbing and fuel system applications where reliability under pressure is non-negotiable. Built for boats, engines, and hydraulic systems that demand leak-free connections in harsh saltwater and freshwater environments, this straight bulkhead union serves as the critical interface between two 6 AN male lines passing through a hull or panel. Whether you're running a high-performance racing engine, upgrading fuel delivery on a center console, or maintaining a commercial fishing vessel, a quality bulkhead fitting is the foundation of safe, dependable operation on the water.

This union features aluminum construction with blue anodized finish, providing corrosion resistance essential in marine saltwater conditions while maintaining a lightweight profile. The straight-flow design minimizes turbulence and pressure drop in fuel, water, or hydraulic lines, critical for maintaining system efficiency and preventing cavitation in high-speed applications. The 6 AN male-to-male bulkhead configuration allows secure panel or hull penetration with flare-sealed connections on both sides, ensuring vibration-proof integrity even in rough seas or under heavy engine load. Anodized aluminum construction resists oxidation and galvanic corrosion better than bare aluminum, extending service life and reducing maintenance downtime.

Anglers and boaters upgrading fuel systems, hydraulic steering, or cooling lines will appreciate this fitting's durability and precision engineering. Installation requires standard bulkhead drilling and is compatible with any system using 6 AN flare fittings—common in custom marine fuel systems, ballast applications, and retrofit work. The compact 2.7 x 1.15 x 3.6 inch footprint fits tight engine compartments without sacrificing functionality. For those building or maintaining boats with high-performance engines or demanding specifications, this XRP-XTREME RACING PROD. union delivers the reliability expected from professional-grade marine hardware.
