16 Male Flare to 20 ORin

The XRP-XTREME RACING PROD. 16 Male Flare to 20 O-Ring adapter fitting is a straight aluminum adapter designed for marine fuel systems, hydraulic lines, and high-pressure fluid transfer applications. This 16 AN male flare to 20 AN male O-ring fitting provides a critical connection point in racing and offshore boating fuel delivery systems where reliability under pressure and temperature extremes is non-negotiable.

Constructed from aluminum with black anodized finish, this adapter resists corrosion in marine salt-air environments while maintaining a lightweight profile essential for performance applications. The O-ring seal design provides superior leak prevention compared to traditional flare-only connections, critical when fuel or hydraulic pressure is involved. The straight configuration allows direct line routing without additional bends or complications in tight engine compartments or below-deck installations.

Serious offshore anglers and performance boaters rely on adapters like this to bridge mismatched line sizes in custom fuel systems or when retrofitting upgraded fuel delivery components. Weekend fishermen upgrading from stock systems to aftermarket performance fuel pumps or secondary fuel systems also depend on reliable adapter fittings to handle the transition between different line standards without pressure loss or leakage.

AN (Army-Navy) standard fittings like this are the industry baseline for racing, high-performance marine, and offshore applications where safety and consistent flow are mandatory. The O-ring modification adds an extra sealing layer, making this adapter suitable for modern fuel-injected engines and pressurized hydraulic systems that demand tighter tolerances than vintage carbureted setups.
