-8AN Female to 3/8inNPT Male Swivel 90 Degree

The -8AN Female to 3/8inNPT Male Swivel 90 Degree adapter from Vibrant Performance is an essential fitting for custom fuel, oil, and coolant line systems in high-performance engine builds and modified vehicles. This compact adapter bridges two industry-standard connection types—AN (Army-Navy) and NPT (National Pipe Thread)—allowing mechanics and enthusiasts to integrate aftermarket fuel rails, turbo oil lines, and remote filtration systems into factory or custom manifolds without costly re-plumbing.

Whether you're installing a standalone EFI system, upgrading to larger fuel injectors, or running synthetic oils through a remote cooler, this fitting ensures reliable, leak-free connections under demanding conditions. Built by Vibrant Performance—a trusted name in fluid transfer systems for racing and street applications—this swivel adapter features a 90-degree elbow geometry that saves space in tight engine bays and under-hood packaging scenarios. The -8AN female port accepts standard braided stainless steel or rubber hose with AN-style flare fittings, while the 3/8-inch NPT male threads directly into block ports, manifolds, or aftermarket adapters.

The swivel design compensates for minor misalignment between hose runs and port locations, reducing installation stress and extending hose service life. Vibrant's precision engineering ensures consistent threads and a precision-machined body that resists galling and delivers a solid seal every time. Mechanics and engine builders will appreciate the reliability and versatility of this adapter in various applications.
