Straight Adapter Fitting ; Size: -8 AN x 1/2in NP

The Vibrant Performance Straight Adapter Fitting in -8 AN x 1/2 inch NP is an essential hydraulic connection component for high-performance fuel, oil, and coolant systems in custom vehicles and racing applications. This adapter bridges incompatible line sizes and port configurations, allowing mechanics and fabricators to consolidate fuel rails, custom plumbing layouts, and aftermarket cooling circuits without requiring complete system redesigns. Whether you're upgrading a carbureted engine to EFI, integrating a secondary fuel pump, or routing coolant through a custom radiator setup, this straight adapter eliminates the need for costly fabrication or multiple adapter chains.

Constructed from aluminum alloy and finished to resist corrosion in engine bay environments, the Vibrant Performance straight adapter uses NPT (National Pipe Thread) on the 1/2-inch port and JIC flare on the -8 AN side, providing a leak-free seal under pressure when properly torqued with appropriate thread sealant. The straight design—as opposed to 90-degree or 45-degree variants—maintains minimal turbulence in fluid flow and reduces fitting profile for tight engine compartment installations where space is premium. The compact 3.5-inch length and 0.05-pound weight add negligible mass while delivering rated performance across typical street and competition fuel pressures up to 100+ PSI.

This fitting is ideal for mechanics building custom fuel systems, turbo conversions, or engine swaps where stock manifold ports don't align with modern fuel rails or aftermarket gauges. It pairs seamlessly with -8 AN hose and fittings found in professional motorsport builds, enabling quick transitions between NPT block ports and standardized AN hose lines. Proper installation requires dry-film sealant on NPT threads and careful torque sequencing to prevent stripped ports—a standard practice in any serious fuel system modification. Stock this adapter in your shop for emergency fuel system repairs, custom plumbing fabrication, or high-end restorations where adaptability and reliability are non-negotiable.
