Adapt. #4 Flare X 1/4npt

The XRP-XTREME RACING PROD. Adapt. #4 Flare X 1/4 NPT adapter is a precision straight fitting engineered for high-performance fuel and fluid systems where reliable, leak-free connections are essential. This 4 AN male to 1/4 inch NPT male adapter bridges two critical port standards in marine powerplants, turbocharged engines, and custom fuel delivery systems where AN hose routing meets NPT threaded ports on carburetors, fuel filters, or manifolds.

Constructed from lightweight aluminum and blue anodized for corrosion resistance in salt-air environments, this adapter maintains structural integrity under the pressure demands of modern racing and marine applications. The flare design on the 4 AN side provides a positive seat against standard AN fittings, while the 1/4 inch NPT male thread ensures a secure connection to NPT-threaded components. At 0.05 lbs and compact dimensions, the fitting integrates cleanly into tight engine bays and fuel system layouts without adding unnecessary bulk or weight.

This adapter is essential for builders custom-routing AN -4 fuel lines to OEM or aftermarket components with 1/4 inch NPT ports—a common scenario in turbocharged installs, fuel system upgrades, and performance carb conversions. The blue anodized finish resists corrosion better than bare aluminum, a practical advantage when exposed to moisture and salt spray on offshore boats or in humid climates. Sold individually, allowing you to build or service your system with precision fittings from a brand trusted in racing applications.
