Plastic T P/L w/1/8NPT

The Plastic T P/L w/1/8NPT from Allstar Performance is a precision adapter tee fitting engineered for fuel, oil, and coolant distribution systems in performance engines and automotive applications. This compact three-port connector allows technicians and builders to split single-line feeds into dual pathways or consolidate dual inputs into one outlet, making it essential for custom fuel systems, engine management setups, and high-flow cooling circuits. The lightweight plastic construction reduces system weight without sacrificing durability, while the combination of pushlock and NPT ports ensures compatibility with both modern quick-disconnect hose systems and traditional threaded fittings.

This adapter tee features dual 3/16-inch female pushlock ports and one 1/8-inch NPT male threaded port, offering maximum versatility in fluid routing scenarios. The nylon hose-rated plastic body is engineered to handle moderate pressures typical of gravity-feed and low-pressure pump systems, while the steel NPT male thread provides corrosion resistance and secure engagement with threaded fittings or gauges. The pushlock design eliminates the need for hose clamps or crimping tools, allowing quick assembly and disassembly during system diagnostics, repairs, or configuration changes. Measuring just 3.45 inches long with a 0.55-inch width profile, this fitting installs in confined engine bay spaces where larger brass or aluminum adapters cannot fit.

Street rods, race cars, and custom fuel systems benefit greatly from this fitting's compact footprint and hybrid port design. Engine builders working with aftermarket fuel pressure regulators, coolant bypass circuits, or oil pressure monitoring systems will find the 1/8-inch NPT port ideal for gauge installation or sensor integration. The pushlock ports accept standard 3/16-inch fuel line and vacuum tubing, making the Plastic T P/L w/1/8NPT compatible with most domestic and import fuel systems that utilize pushlock quick-disconnect fittings. For optimal performance, ensure all hose connections are fully seated on the pushlock ports and verify NPT fitting torque with threadlocker compound where vibration is a concern.
