Straight Adapter FItting ; Size: -6 AN x 3/8in NP

The Vibrant Performance Straight Adapter Fitting in -6 AN x 3/8in NP is a precision hose adapter designed for high-performance fuel, coolant, and fluid distribution systems in custom vehicles and engine builds. This straight connector allows seamless integration between -6 AN hose lines and 3/8-inch National Pipe (NP) threaded ports, making it essential for builders transitioning between modern braided hose systems and legacy or OEM port configurations.

Constructed from precision-engineered aluminum or steel (depending on application pressure), this fitting minimizes turbulence and pressure drop during circulation. The -6 AN side accommodates standard 3/8-inch braided hose with crimp or push-lock fittings, while the 3/8-inch NP male thread provides a leak-free seal when torqued to OEM specifications. Vibrant Performance's manufacturing tolerances ensure concentricity and thread integrity across pressure cycling, preventing weeping or failure under sustained boost, fuel delivery demands, or high-temperature coolant flow.

Mechanics and engine builders will find this adapter invaluable when upgrading fuel systems on classic muscle cars, modernizing vintage engine blocks, or fabricating custom performance applications. Its compact footprint fits tight engine bay layouts without requiring extended hose runs or custom bracketry, making it a practical choice for various automotive applications.
