Adapter Fitting -16 Male to -12 O-Ring Port 45Deg

The Adapter Fitting -16 Male to -12 O-Ring Port 45Deg by XRP-Xtreme Racing Products is a precision hydraulic adapter designed for high-performance fuel and fluid line systems in custom automotive builds. This fitting bridges two different port sizes and thread standards, making it essential for mechanics and engine builders who integrate aftermarket fuel injection systems, custom fuel rails, and performance cooling circuits into modified engines.

Engineered with a 45-degree elbow geometry, this adapter fitting reduces strain on hose runs and fluid lines by allowing optimal routing in tight engine compartments where straight connections would cause kinks or excessive bends. The -16 male thread (7/8"-16 SAE) connects to your primary line, while the -12 O-ring port (3/4" SAE) accommodates the secondary component, utilizing O-ring seal technology to minimize seepage under fuel pressure or coolant system demands.

This adapter is ideal for fuel system upgrades, custom radiator and overflow tank installations, and aftermarket cooling systems. Its 45-degree angle design is critical for high-vibration environments, distributing stress more evenly than 90-degree alternatives, which can extend hose and component lifespan in turbocharged and supercharged applications.
