12an X 8an Fitting

The 12AN X 8AN Fitting by KINSLER is a precision-engineered hydraulic and pneumatic adapter designed for high-performance fuel, oil, and brake line applications in tactical vehicles, law enforcement equipment, and military platforms. This adapter serves as a critical junction component in systems where reliable pressure containment and flow regulation are non-negotiable—whether in armored personnel carriers, tactical support vehicles, or specialized hydraulic brake assemblies. Built to exacting standards, the 12AN X 8AN fitting ensures secure, leak-free connections in demanding operational environments where system failure is not an option.

Constructed from forged aluminum or steel depending on application requirements, the KINSLER fitting features dual AN thread ports—the primary 12AN size (3/4-inch thread) and secondary 8AN size (1/2-inch thread)—allowing stepped pressure transitions across system branches. The AN (Army-Navy) standard thread specification provides precise sealing geometry, critical for maintaining system integrity under sustained pressure and thermal cycling. Weighing only 0.08 lbs, the compact 1.95 x 1.45 x 2.6-inch form factor minimizes installation space while maximizing flow capacity, making it ideal for tight engine bays and modular tactical systems where weight and packaging efficiency directly impact vehicle performance and portability.

Vehicle technicians, military automotive specialists, and tactical equipment integrators rely on the KINSLER 12AN X 8AN fitting for fuel distribution manifolds, brake line consolidation, and hydraulic proportioning applications in both rotary and fixed-wing military platforms. Installation requires standard AN wrench fitments and torque specifications aligned to system pressure ratings—typically 24–36 ft-lbs depending on material composition. Compatibility spans diesel and gasoline fuel systems, mineral and synthetic hydraulic fluids, and pressures up to 3000 PSI, making it suitable for everything from light tactical support vehicles to heavy armored transport. Verify your specific system pressure rating and fluid type before ordering to ensure optimal performance and longevity.
