#10 Male Flr to #12 ORB Str Fitting

The #10 Male Flr to #12 ORB Str Fitting is a precision adapter designed for high-performance fuel system and fluid line applications where AN (Army-Navy) port standards must transition between different sizes. This straight configuration eliminates bends and reduces pressure drop, making it essential for builds requiring efficient flow management across incompatible hose or line diameters. Built by XRP-XTREME RACING PROD., a trusted manufacturer in motorsports plumbing solutions, this fitting serves engine builders, fuel system installers, and performance enthusiasts who demand reliability under demanding conditions.

Engineered from aluminum and finished in black anodized coating for corrosion resistance and durability, the #10 Male Flr to #12 ORB Str Fitting employs an O-ring boss (ORB) design on the #12 outlet to ensure leak-free seals without thread sealant tape. The straight geometry eliminates flow turbulence at the transition point, critical for maintaining fuel pressure consistency in carbureted and fuel-injected applications. At just 0.1 lbs, this compact adapter integrates seamlessly into tight engine bays while the male flare input (#10 AN) accepts standard -10 hose or hardline, and the #12 ORB output connects directly to receptacle ports on fuel rails, regulators, or block fittings.

This fitting is indispensable for custom fuel system fabrication, engine swaps, and race car builds where factory ports or existing hardlines won't accommodate newer or larger-displacement fuel delivery requirements. The combination of male flare and O-ring boss construction makes it compatible with both legacy -10 AN fuel lines and modern -12 AN components, offering flexibility for transitional modifications. Installation requires no special tools—simply thread the male flare input into a -10 female flare port and insert the ORB end into a -12 ORB receptacle with a crush washer, ensuring a secure, maintenance-free connection that withstands high vibration and thermal cycling.
