16AN to 12AN 3/4NPT Straight Male to Male

The 16AN to 12AN 3/4NPT Straight Male to Male fitting from REDHORSE PERFORMANCE is a precision hydraulic and fuel system adapter engineered for professional-grade applications in tactical vehicles, high-performance machinery, and law enforcement equipment. This reducer adapter bridges two different AN port sizes while maintaining a secure NPT (National Pipe Thread) connection, making it essential for mechanics and technicians who need to downsize line configurations without sacrificing system integrity. Built for environments where reliability is non-negotiable—from military logistics to specialized tactical platforms—this fitting delivers the dependable performance demanded by operators who trust their equipment under pressure.

Constructed with male-to-male threading on both ends, the 16AN to 12AN adapter allows seamless connection between larger 16AN ports and smaller 12AN systems, with the 3/4NPT specification providing a proven industrial-standard seal. REDHORSE PERFORMANCE fittings are manufactured to exacting tolerances, utilizing hardened aluminum or steel construction that resists corrosion and maintains pressure integrity across temperature extremes and high-vibration environments typical of tactical and military operations. The straight configuration eliminates weak points created by angled connections, reducing leak potential and simplifying installation in compact engine bays or equipment frames where space and reliability are both critical factors.

This adapter is ideal for custom fuel system builds, hydraulic line reconfiguration, and equipment retrofitting in law enforcement and military applications where OEM fittings may not match aftermarket or tactical components. Technicians and equipment specialists benefit from the compact 2.75-inch length and lightweight 0.17-pound profile, which ensures minimal weight penalty while fitting into tight installations. Compatible with standard -16 and -12 AN hose and hard-line assemblies, the fitting integrates seamlessly into existing systems, requiring only standard wrenches for installation and routine maintenance checks—making it a reliable choice for field technicians and depot-level repairs.
