1/4npt Female Tee adapt black

The 1/4 NPT female tee adapter in black from REDHORSE PERFORMANCE is an essential manifold component for custom fuel, coolant, vacuum, and auxiliary fluid distribution systems in high-performance and modified vehicles. This adapter serves as a three-way junction point, allowing you to split a single line into two outlet ports while maintaining the same inlet connection—a critical feature for builders expanding engine bay plumbing without adding excessive complexity. Whether you're upgrading a fuel system, installing auxiliary gauges, routing catch-can lines, or managing intercooler piping, the tee adapter provides reliable flow distribution at junction points.

Constructed from high-strength aluminum and finished in black anodize, this adapter resists corrosion and integrates seamlessly into modern engine bay aesthetics. The 1/4 inch NPT (National Pipe Thread) female connection on all three ports ensures compatibility with standard hose barb fittings, quick-disconnects, and gauge takeoffs commonly used in performance applications. NPT threads create a tapered metal-to-metal seal when properly torqued, eliminating the need for additional sealant tape in most fuel and coolant applications. The compact 3 x 1 x 4.5 inch footprint allows flexible mounting in tight spaces, while the 0.088 lb weight keeps overall system mass minimal—important for weight-conscious builds.

Engine builders, tuners, and DIY enthusiasts benefit most from this adapter when designing custom fuel systems with dual returns, installing oil-cooler setups, routing wastegate vent lines, or creating redundant gauge feed points. It pairs effectively with braided stainless steel hose, aluminum hard-line tubing, or rigid plastic piping depending on your application's pressure and temperature demands. Verify hose barb compatibility with your chosen fittings before final assembly; 1/4 NPT female ports typically accept barbs rated for -4 AN equivalent sizing. REDHORSE PERFORMANCE adapters are trusted throughout the motorsport and street modification communities for reliability under sustained pressure and thermal cycling.
