Straight Adapter Fitting ; Size: -10AN x 1/2in NP

The Vibrant Performance straight adapter fitting (-10AN x 1/2in NP) is a precision hose connector engineered for high-pressure hydraulic and fuel line systems requiring reliable, leak-free connections. Designed for builders and technicians working with race engines, custom fuel systems, and hydraulic control circuits, this adapter bridges two industry-standard port sizes to streamline system integration. Its straightforward 1:1 configuration eliminates flow disruption and simplifies installation in space-constrained engine bays.

Crafted from lightweight aluminum and finished in black anodized coating, the -10AN x 1/2in NP straight adapter delivers durability against corrosion while maintaining minimal weight penalty for performance applications. The -10AN (AN10) port accepts industry-standard AN hose and fittings with a 10-size designation, while the 1/2-inch NPT (National Pipe Thread) male end threads directly into NPT-compatible ports commonly found on engine blocks, manifolds, and aftermarket accessories. The straight design ensures proper hose routing and eliminates the pressure losses or turbulence associated with angled fittings, critical for maintaining fuel pressure consistency and system efficiency.

This adapter is ideal for custom fuel injection systems, dry-sump or wet-sump conversions, coolant bypass circuits, and boost control lines where AN plumbing meets factory or aftermarket NPT boss ports. Weighing only 0.06 lbs, it introduces negligible mass while providing a secure, repeatable connection point. Installers should apply thread sealant compatible with their fluid type and confirm NPT port cleanliness before assembly to achieve optimal seal integrity and prevent system leaks under peak operating pressures.
