Endura Adapter Fitting #6 to 1/4 NPT Straight

The Endura Adapter Fitting #6 to 1/4 NPT Straight is a precision hose adapter designed for use in fuel, oil, coolant, and transmission fluid systems. It is ideal for high-performance and street-driven vehicles, facilitating the transition from -6 AN (JIC) hose fittings to 1/4-inch NPT ports. This makes it a valuable component for engine swaps, fuel system upgrades, and custom plumbing scenarios.

The straight-port configuration of this adapter minimizes turbulence and pressure drop, simplifying installation in tight engine bays. The NPT port features tapered threads that create a secure mechanical fit, while the -6 AN side is compatible with standard braided hose with JIC fittings. This design is favored in professional racing and restoration shops for its reliability.

Builders and mechanics will find this adapter particularly useful when connecting aftermarket fuel pressure gauges, oil coolers, or transmission coolers to factory NPT ports. It is commonly utilized during engine conversions, including LS swaps and crate motor installations, ensuring a seamless integration with existing systems.
