4AN 90Deg Male Adapter to 1/4in NPT Male Blue

The 4AN 90Deg Male Adapter to 1/4in NPT Male Blue from REDHORSE PERFORMANCE is a precision fluid-line fitting engineered for custom automotive fuel, coolant, and hydraulic systems. Mechanics and performance enthusiasts rely on this adapter when transitioning between AN (Army-Navy) tubing standards and traditional NPT (National Pipe Tapered) threaded ports commonly found on carburetors, fuel pressure regulators, and aftermarket gauges.

This right-angle configuration saves space in tight engine bays where straight runs aren't practical, making it indispensable for modern engine swaps, fuel system upgrades, and forced-induction builds. Constructed from aluminum with a vibrant blue anodized finish, this 4AN-to-1/4" NPT adapter combines lightweight durability with superior corrosion resistance and thermal stability. The precise machining of both the 4AN port and the 1/4" NPT male threads ensures zero-play connections and positive seat engagement, critical when working with fuel under pressure or coolant in high-temperature environments.

Redhorse Performance's reputation for meticulous tolerances means this adapter will maintain its seal integrity through decades of thermal cycling and vibration. This adapter shines in EFI fuel system retrofits, where you're replacing carb-era NPT ports with modern AN braided hoses. Its design is particularly beneficial for those looking to enhance their vehicle's performance and reliability.
