#8 Bulkhead Flare Union

The #8 Bulkhead Flare Union by XRP-XTREME RACING PROD. is a critical hydraulic and fuel system component engineered for high-performance automotive applications where reliability and leak-free connections are non-negotiable. This straight bulkhead fitting allows you to pass 8 AN (AN8) fluid lines through a firewall, chassis panel, or engine bay partition while maintaining pressure integrity in demanding race, street rod, and custom vehicle builds. Whether you're running a custom fuel system, brake hardline configuration, or transmission cooler circuit, this union eliminates the need for external elbows on the panel's opposite side.

Manufactured from aluminum and finished in blue anodize, the #8 Bulkhead Flare Union features male 8 AN connections on both sides, with the bulkhead body itself threaded to pass cleanly through a drilled hole in your firewall or panel. The straight design (as opposed to an elbow) preserves line routing efficiency and minimizes turbulence in fuel or coolant circuits. Blue anodizing provides corrosion resistance and a professional appearance while keeping weight minimal—critical in race environments where every fraction of a pound counts. The 0.1 lb unit is compact (2.7 × 1.3 × 3.7 inches), making it ideal for tight engine compartments and complex plumbing layouts.

Mechanics and fabricators building fuel injection systems, custom cooling loops, or race-spec brake lines rely on XRP bulkhead unions to seal bulkheads without adding external fittings or adapters. This fitting is essential for clean, professional builds where internal panel space is limited and external routing would compromise aerodynamics or aesthetics. The AN8 size handles flows and pressures typical of modern EFI fuel systems, turbo boost circuits, and performance transmission coolers. Installation requires only a standard wrench to thread the bulkhead body through your panel and tighten the 8 AN male connectors; ensure proper flare preparation on all hoses to achieve leak-free seals.
