Adapter Fitting Bulkhead Straight 12an

The EARLS Adapter Fitting Bulkhead Straight 12AN is a precision hydraulic and fuel line adapter designed for high-performance automotive and motorsport applications where reliable, leak-free connections are critical. This male-to-male bulkhead fitting serves as an essential component in fuel systems, brake lines, and cooling circuits, enabling seamless integration between two 12 AN hose ends while maintaining a compact, panel-mount footprint. Whether you're building a custom race engine bay, retrofitting a fuel delivery system, or assembling a high-pressure hydraulic circuit, this adapter provides the dependable interface professional technicians and enthusiasts demand.

Constructed from aluminum and finished in black anodized coating, the adapter delivers corrosion resistance and a clean, professional appearance while maintaining lightweight properties crucial in performance applications. The straight bulkhead design allows flush panel mounting without the sharp angles or protrusions of elbow fittings, reducing installation footprint and minimizing snagging hazards in tight engine compartments. The 12 AN (JIC -12) port size handles high-flow demands with the dimensional stability and proven durability that EARLS fittings are recognized for throughout the motorsport industry, ensuring secure connections that withstand vibration, temperature cycling, and sustained pressure without weeping or separation.

This fitting is ideal for custom fuel injection systems, supercharger intercooler loops, transmission coolers, and remote reservoir plumbing where space efficiency matters and panel-mount consolidation reduces line clutter. Installation is straightforward—apply thread sealant (PTFE tape or liquid thread sealant) to the male ends, insert through your panel, and tighten with appropriate AN wrenches to the correct torque specification. Compatible with any standard 12 AN hose, adapter, or component featuring matching JIC -12 male ports, this single-piece fitting eliminates the need for multiple adapters and reduces potential leak points, making it an economical upgrade for serious builds.
