1/8in FM Tee NPT Adapter Black

The 1/8in FM Tee NPT Adapter Black by REDHORSE PERFORMANCE is a critical fluid distribution component designed for custom fuel, coolant, and brake line routing in high-performance automotive builds. This T-junction adapter serves mechanics and enthusiasts who need precise, reliable connections when integrating aftermarket fuel systems, turbocharger intercoolers, or custom cooling circuits into modified engines. Whether you're fabricating a fuel manifold setup or consolidating multiple line runs into a single feed source, this adapter provides the structural integrity and leak-free performance that separates professional-grade builds from amateur installations.

Constructed from durable black-anodized aluminum alloy, the 1/8in FM Tee NPT Adapter features NPT (National Pipe Thread) male connections on all three ports, allowing seamless integration into standard automotive plumbing systems without adapters at each junction. The tee configuration distributes flow equally across two outlet ports while accepting a single inlet, making it ideal for pressure-equalization applications, surge tank feeds, or multi-destination fuel distribution networks. The compact 1/8-inch nominal size minimizes installation footprint while maintaining adequate flow capacity for street and track applications, and the black powder-coat finish resists corrosion and maintains a professional appearance in engine bay or custom fabrication work.

Engine builders, fuel system integrators, and fabrication shops standardize on REDHORSE adapters for their consistency and reliability across diverse cooling and fuel applications. Installation requires NPT-compatible hoses or hard-line fittings; verify your feed and return line sizes before assembly to ensure proper torque values and port alignment. Weighing just 0.06 pounds, this adapter adds negligible mass while eliminating the need for multiple smaller fittings, reducing joint count and leak potential—a decisive advantage in high-vibration or high-pressure environments like forced-induction or race-prepped platforms.
