3AN Bulkhead Adapter Black Male Male Straight

The 3AN Bulkhead Adapter Black Male Male Straight by REDHORSE PERFORMANCE is an essential fitting for fuel system and hydraulic line integration in custom engine builds and performance vehicle modifications. Whether you're fabricating a fuel cell installation, upgrading fuel injection lines, or routing custom brake and clutch systems, this bulkhead adapter provides a reliable, leak-free connection point where two male -3 AN-threaded lines need to pass through a firewall, floor pan, or engine bay bulkhead.

Mechanics and fabricators rely on bulkhead adapters to create clean, professional-grade plumbing in competition vehicles, turbocharged builds, and street performance applications. This -3 AN male-to-male straight adapter features a precision-machined aluminum body with a hard anodized black finish that resists corrosion and UV degradation in engine compartments exposed to fuel, oil, and extreme temperatures. The straight configuration (zero bend angle) allows dual male -3 fittings to connect end-to-end through a single bulkhead opening, eliminating the need for separate bulkhead couplers on each side and reducing line clutter in tight engine bays.

The compact 2.75-inch length and lightweight construction make it ideal for weight-conscious builds, while the male-to-male design accommodates both -3 female-threaded line ends without requiring intermediate adapters, simplifying your fuel or hydraulic routing significantly. This adapter suits EFI fuel system installations and is perfect for those looking to enhance their vehicle's performance and reliability.
