3AN Male to 1/8in NPT FM Gauge Adapter STR Blue

The 3AN Male to 1/8in NPT Female Gauge Adapter STR Blue from REDHORSE PERFORMANCE is a precision hydraulic and pneumatic fitting designed for law enforcement, military, and specialized equipment operators who demand reliable pressure monitoring across mismatched connection standards. This straight adapter bridges the gap between AN (Army-Navy) flange connections and NPT (National Pipe Thread) gauge ports, eliminating the need for multiple adapter stacks that compromise system integrity and add unnecessary weight to tactical platforms, mobile command units, and field-deployed hydraulic systems.

Constructed from aerospace-grade materials with corrosion-resistant blue anodizing, the adapter features a true straight (STR) body that minimizes turbulence and pressure drop during real-time gauge readings—critical when monitoring brake systems, suspension hydraulics, or pneumatic tool pressures in field conditions. The 3AN male connection (compatible with standard -3 hose and bulkhead fittings) threads directly into 1/8-inch NPT female gauge ports without requiring thread sealant tape on the AN side, preserving connection integrity under vibration and thermal cycling that degrades lesser adapters. REDHORSE PERFORMANCE's manufacturing tolerances ensure zero-leak performance and repeatable pressure accuracy essential for tactical maintenance and system diagnostics.

Military mechanics, armored vehicle technicians, and equipment specialists benefit most from this adapter when retrofitting modern pressure gauges to legacy systems or integrating aftermarket monitoring into custom hydraulic platforms. Installation is straightforward—hand-tightened with a wrench if needed—and the compact 2.835-inch length prevents interference in tight engine bays or equipment compartments. Weighing only 0.083 lbs, it adds negligible mass while delivering the reliability that life-safety equipment demands in high-stress operations.
