-8AN Female to 3/8inNPT Male Swivel Fitting

The -8AN Female to 3/8in NPT Male Swivel Fitting by Vibrant Performance is a precision hydraulic adapter engineered for professional-grade fluid transfer systems, fuel lines, and custom plumbing applications. This straight adapter connects 8 AN female swivel ports to standard 3/8 inch NPT male threads, making it essential for builders and technicians who need reliable, leak-free connections across mismatched port configurations. Whether you're assembling a high-performance fuel system, hydraulic brake line, or custom coolant circuit, this fitting bridges the gap between two industry-standard thread families without compromise.

Constructed from durable aluminum and finished in black anodize, this adapter combines corrosion resistance with lightweight strength. The swivel design on the 8 AN female end allows rotation for stress-free installation and alignment, reducing hose kinking and vibration-induced fatigue during operation. The 3/8 inch NPT male thread provides a sealed, tapered connection that tightens progressively—no ferrule or compression fitting required. The black anodized finish protects against oxidation and enhances aesthetics while maintaining full functionality in demanding environments, from engine bays to hydraulic test benches.

This fitting is ideal for fuel system builders, performance technicians, hydraulic engineers, and motorsports enthusiasts who demand precision and reliability under pressure. Installation is straightforward—apply appropriate sealant tape or thread compound to the NPT male end and torque to the system's specifications. The swivel female end accepts standard 8 AN hose with -8 fittings, making it compatible with both braided stainless steel and rubber hose assemblies. For anyone upgrading fuel lines, intercooler circuits, or brake hydraulics, this adapter delivers the flexibility and durability needed for professional-quality results.
