3AN STR Male Adapter 1/4in NPT Male Blue

The 3AN STR Male Adapter 1/4in NPT Male Blue from REDHORSE PERFORMANCE is a precision hydraulic and pneumatic fitting designed for professional-grade fluid transfer systems in tactical, military, and law enforcement equipment. This straight male adapter serves as a critical junction point in fuel systems, air supply lines, and fluid delivery networks where reliable connection integrity is non-negotiable. Whether you're building custom tactical vehicle fuel systems, maintaining mobile command centers, or servicing specialized equipment in the field, this adapter ensures secure, leak-free performance under demanding operational conditions.

Engineered with a 1/4-inch NPT (National Pipe Tapered) male thread, the 3AN STR adapter features the distinctive blue anodized finish that REDHORSE PERFORMANCE applies for corrosion resistance and identification in high-visibility operational environments. The straight configuration (STR) eliminates offset angles, reducing turbulence and pressure drop in critical fluid systems while simplifying installation in confined spaces typical of tactical vehicle platforms. Rated for both hydraulic and pneumatic applications, this adapter handles the thermal cycling and pressure fluctuations inherent to field operations, making it suitable for fuel distribution, brake assist systems, and auxiliary air supply lines where performance cannot be compromised.

Tactical operators, armored vehicle specialists, and maintenance personnel standardize on REDHORSE PERFORMANCE adapters for their proven reliability in extreme conditions. The compact 3.1 x 1.1 x 3.9-inch footprint and lightweight 0.05-pound design facilitate integration into space-constrained installations without sacrificing structural integrity. This adapter is compatible with any system utilizing 1/4-inch NPT male connections and accepts industry-standard AN hose fittings, making it an ideal replacement or upgrade component for military-specification fluid transfer networks. Installation requires only standard wrenches—no specialized tooling necessary for field maintenance or system modifications.
