1/8in FM Tee NPT Adapter Blue

The 1/8in FM Tee NPT Adapter Blue from REDHORSE PERFORMANCE is an essential fluid management component for custom fuel, coolant, and hydraulic systems in high-performance vehicles. Whether you're building a fuel system for a turbocharged engine, upgrading your cooling circuit, or installing remote gauges and sensors, this NPT tee adapter provides a reliable junction point where three fluid lines meet. Designed for mechanics and enthusiasts who demand precision plumbing on modified vehicles, this compact adapter eliminates the need for cobbled-together solutions and delivers professional-grade reliability.

This adapter features a 1/8-inch female pipe thread (FM) configuration with National Pipe Thread (NPT) standard compatibility, allowing seamless integration with industry-standard fittings and hose barbs. The blue anodized finish provides corrosion resistance and helps visually distinguish coolant or fuel lines in complex engine bay layouts, improving both maintainability and safety. The compact 2.85 x 1.1 x 3.8-inch footprint and minimal 0.06-pound weight make it ideal for tight engine bay installations where space is at a premium. REDHORSE PERFORMANCE's engineering ensures leak-free connections through precision-machined ports and proper NPT tapered thread engagement.

This tee adapter excels in custom cooling system upgrades, aftermarket fuel system installations, and auxiliary gauge setups on turbo builds, LS swaps, and radical engine modifications. It pairs effectively with remote thermostats, fuel pressure regulators, line T-fittings, and diagnostic sensor ports where three-way fluid distribution is required. Installation is straightforward using standard NPT wrenches or hose barb adapters; ensure proper PTFE tape or pipe thread sealant application for watertight seals. The blue finish complements modern engine bay aesthetics while the durable construction withstands high-pressure fuel systems and elevated coolant temperatures found in aggressive performance applications.
