-12 Male 90 Deg. To -10 O-Ring Boss

The XRP -12 Male 90 Deg. To -10 O-Ring Boss adapter is a precision hydraulic fitting designed for custom fuel, coolant, and brake system installations in modified and race vehicles. This 90-degree angle adapter bridges two different AN port sizes—converting -12 AN male ports to -10 AN O-ring boss configurations—making it essential for builders who need flexible plumbing solutions when factory routing won't work or when consolidating multiple smaller-diameter lines into larger distribution blocks. Whether you're installing a custom fuel rail, upgrading a cooling system, or fabricating a motorsports-grade brake circuit, this adapter provides the directional control and size conversion necessary to achieve clean, leak-free connections in tight engine bays.

Manufactured from lightweight aluminum and finished in black anodize, the -12 Male 90 Deg. To -10 O-Ring Boss adapter combines durability with minimal weight penalty—a critical consideration for performance applications where every pound affects handling and efficiency. The 90-degree elbow design eliminates the need for separate hose bends or tubing elbows, reducing pressure drop and potential failure points while improving underhood aesthetics. The O-ring boss end ensures a metal-to-metal seal that withstands high-pressure cycles without relying on thread sealant, making it ideal for systems running turbocharged or supercharged engines where pressure spikes and vibration demand absolute reliability. XRP's anodized finish resists corrosion and provides visual continuity with other aluminum hydraulic components in modern engine bays.

Engine builders, fabricators, and performance shops rely on this adapter when custom-routing fuel, water, or oil lines through constraint-heavy chassis layouts—particularly in LS swaps, engine conversions, and full system rebuilds where original component geometry doesn't align with new powerplant placement. Its compact footprint (2.7 x 1.4 x 4 inches) fits tight quarters without sacrificing flow characteristics, and the -12 to -10 size transition accommodates modern fuel injection systems, auxiliary water pumps, and remote oil filtration setups. Installation requires standard AN wrench sizes and basic hose assembly knowledge; the O-ring boss connection seats firmly without over-torquing, minimizing risk of thread galling. Verify your system's pressure rating and hose diameter compatibility before ordering to ensure seamless integration with existing or new components.
