8an Str Male Bulkhead Fitting Blue

The 8AN Str Male Bulkhead Fitting Blue from REDHORSE PERFORMANCE serves as a critical junction component in high-performance fuel, coolant, and hydraulic line systems where clean, leak-free connections are non-negotiable. This straight male bulkhead fitting is engineered for builders and mechanics who demand reliability in custom fuel system installations, whether you're fabricating a competition fuel cell setup, upgrading a carbureted engine, or integrating aftermarket cooling systems. The bulkhead design allows clean panel or firewall-mounted installation without requiring excessive tubing runs, saving weight and complexity in tight engine bays.

Constructed from aerospace-grade materials with anodized blue hard-coat finish for corrosion resistance, the 8AN Str Male Bulkhead Fitting delivers the precision machining REDHORSE is known for in the motorsports community. The AN (Army/Navy) 8 sizing standard equates to 1/2-inch nominal tubing compatibility, and the straight male configuration accepts hose ends or tube adapters on the interior while threading directly into a female bulkhead receptacle on the panel exterior. This design eliminates mechanical stress concentration at elbows and reduces pressure drop compared to traditional 90-degree fittings, critical when running fuel at higher flow rates or in systems with tight margin tolerances.

Mechanics, engine builders, and custom fabricators benefit most from this fitting when designing fuel system pans, transmission coolers, or intercooler plumbing where external bulkhead routing simplifies assembly and serviceability. Installation is straightforward—thread the male side into a pre-drilled, tapped female receptacle on your panel or tank, then secure interior hose or AN tube fittings to the protruding male end. The compact dimensions (3.75 x 1.4 x 4.1 inches) and light weight (0.105 lbs) make it ideal for weight-conscious builds, and its blue finish provides excellent visual identification in complex fuel and coolant networks for maintenance and troubleshooting.
