Performance and reliability notes

While results depend on your exact configuration, pairing a precise thread with a robust contact surface can help maintain orderly fuel routing. The combination of a strong aluminum body, consistent flare seating, and a tidy finish contributes to a clean, organized setup that you can inspect at a glance.

Material and finish you can trust

The aluminum 6061-T6 alloy offers a favorable strength-to-weight ratio and good corrosion resistance. The anodized black surface not only looks durable but helps resist surface oxidation in hot, humid environments. The 37-degree flare seal is designed for reliable seating across cycles.

Installation tips

Prepare mating surfaces, clean hoses, and use proper torque when tightening. Align hoses to avoid bending, and check for leaks after initial startup. This adapter is intended for bulkhead-style connections in fuel systems.

Compatibility notes

Designed to pair with standard 8AN hoses and fittings that use the 3/4-16 UNF thread. Verify application clearances and ensure the firewall or bulkhead location can accommodate a straight bulkhead adapter.
