-8AN Male 3/8in NPT 45 Degree Hose End Fitting

The -8AN Male 3/8in NPT 45 Degree Hose End Fitting from VIBRANT PERFORMANCE is a precision adapter engineered for custom fuel, coolant, and brake line routing in high-performance automotive applications. This fitting solves a critical challenge: connecting AN (Army-Navy) hose standards to NPT (National Pipe Thread) ports found on engine blocks, fuel pressure regulators, and aftermarket gauges. Whether you're building a fuel system for a turbocharged engine swap, upgrading to a remote oil cooler setup, or installing a custom cooling loop, this 45-degree adapter eliminates the need for multiple fittings and ensures leak-free connections under pressure and vibration.

Constructed from lightweight aluminum with black anodized finish, the -8AN Male 3/8in NPT 45 Degree Hose End Fitting combines durability with corrosion resistance—essential for underhood environments exposed to heat cycling and moisture. The 45-degree angle geometry allows for space-efficient routing around engine bay obstacles while the male NPT thread (3/8 inch) seats directly into female NPT ports with a mechanical seal that tightens reliably across pressure ranges typical of fuel systems, coolant circuits, and brake applications. The -8AN hose end accepts standard 8 AN hose with appropriate crimped or AN-style fittings, creating a modular, reusable connection system that professional fabricators and serious enthusiasts trust for repeatability and reliability.

This fitting is ideal for EFI conversions, fuel system upgrades, boost cooling circuits, and engine bay plumbing on LS-swapped vehicles, vintage restorations, and race cars where compact, vibration-resistant connections are non-negotiable. The angled design is particularly valuable in tight engine compartments where straight fittings would interfere with headers, intake manifolds, or belt systems. Installation requires only a wrench on the NPT end and proper hose assembly on the AN side; always verify NPT thread direction and apply appropriate thread sealant for fuel or coolant applications to ensure pressure integrity and prevent weeping over time.
