AN to NPT Straight #8 x 1/4

The TRIPLE X RACE COMPONENTS AN to NPT Straight #8 x 1/4 adapter is a precision-engineered hose fitting engineered to bridge AN (Army-Navy) male threads to NPT (National Pipe Thread) male ports in high-performance hydraulic and fuel systems. This adapter serves critical applications across tactical vehicles, high-flow weaponry systems, and performance-driven equipment where reliable fluid pathway connections are non-negotiable. The straight configuration eliminates directional complexity, making installation straightforward in confined spaces where angled fittings create packaging conflicts.

Sized at #8 AN (which converts to 1/2-inch OD tube) mating to 1/4-inch NPT ports, this adapter handles moderate flow rates suitable for fuel supply lines, cooling loops, and auxiliary hydraulic circuits. The aluminum construction balances corrosion resistance with weight savings—a critical consideration in mobile tactical platforms where system weight directly impacts fuel efficiency and operational range. The compact footprint (2.7 x 1 x 3.1 inches) and minimal mass (0.02 lbs) minimize space requirements and load penalties, allowing integration into systems already operating near weight or dimensional limits.

This adapter is purpose-built for operators and technicians managing custom fuel systems, mobile command platforms, and specialized recovery equipment that demand thread-standard conversion without performance compromise. AN/NPT mismatch is common in retrofit scenarios where newer components with AN ports must connect to legacy NPT infrastructure, or where system designers source components from different manufacturers using competing thread standards. A properly sealed adapter eliminates leakage points in high-vibration environments where mechanical stress regularly tests fitting integrity.

Part Number HF-90082BLK identifies this specific straight-thread configuration, enabling precise parts ordering and inventory management across fleet operations. Proper installation requires compatible thread sealant rated for the fluid type in use—PTFE tape for dry gases, anaerobic sealant for petroleum products, ensuring long-term seal integrity under operational stress.
