St. #8 > 1/4 Npt Adpt.

The St. #8 > 1/4 NPT Adapter by EARLS is an essential fitting for any high-performance fuel system, coolant line, or fluid transfer application where port size conversion is critical. Whether you're building a custom engine bay, upgrading fuel delivery on a modified vehicle, or integrating aftermarket gauges and sensors, this adapter bridges the gap between SAE straight thread and NPT (National Pipe Thread) standards. Mechanics and fabricators rely on EARLS adapters to ensure leak-free connections in demanding automotive environments where precision and durability matter most.

This adapter converts a size #8 SAE straight thread port to a 1/4 inch NPT connection, accommodating a wide range of aftermarket components and OEM specifications. EARLS fittings are engineered from premium materials and manufactured to tight tolerances, ensuring reliable sealing without thread sealant degradation under high pressure and temperature cycles. The compact 1.6 x 1 x 3.1 inch design fits in confined engine compartment spaces, while the lightweight 0.03 lbs construction adds negligible weight to your vehicle. The precision machining and proven EARLS quality standard make this adapter suitable for fuel injection systems, oil cooler lines, transmission coolers, radiator bypass circuits, and custom sensor installations.

Technicians and enthusiasts working on fuel system upgrades, engine swaps, or performance cooling modifications benefit from this adapter's versatile port compatibility. It pairs seamlessly with EARLS hose fittings, block adapters, and manifold components commonly used in street rods, race cars, and turbocharged builds. Installation is straightforward for those with basic mechanical knowledge; simply thread the SAE #8 end into your application port and connect 1/4 NPT components to the opposite end. Always verify your specific system requirements and fluid compatibility before assembly to guarantee optimal performance and safety in your automotive project.
