#20 Male Flr to #16 ORB Str Fitting

The #20 Male Flr to #16 ORB Str Fitting (XRP980021) is a precision AN adapter designed for high-pressure fuel, oil, and coolant systems on performance marine engines and racing applications. Built by XRP-XTREME RACING PRODUCTS, this straight-port adapter bridges two common AN line sizes—#20 SAE male flange and #16 O-ring boss male—enabling flexible hose routing and component compatibility across modern powerboat and performance boat platforms. Anglers and boaters operating turbocharged or supercharged engines depend on these adapters to maintain system integrity under extreme operating conditions.

Machined from aluminum and finished in black anodize, the #20 Male Flr to #16 ORB Str Fitting resists corrosion in saltwater and fresh water environments while delivering reliable leak-free connections at race-proven pressures. The straight-port design eliminates flow disruption and pressure loss, critical for engines running fuel injection systems, supercharger intercoolers, or high-flow oil coolers where efficiency directly impacts performance and engine longevity. Black anodize provides both durability and aesthetic integration with modern engine bay setups. Weighing only 0.19 lbs, the compact 3.8 x 1.7 x 5.7-inch form factor simplifies installation in confined engine compartments typical of performance center consoles and tunnel hulls.

Marine mechanics, performance shops, and experienced boaters select XRP adapters when upgrading fuel systems, installing aftermarket oil coolers, or reconfiguring engine bay plumbing on high-horsepower applications. The #16 ORB (O-ring boss) connection seals without tape or dope, enabling quick assembly and field adjustments on the water or at the dock. This adapter suits any application where size transition between #20 and #16 AN lines is required—from twin-engine performance boats to closed-loop cooling systems. Installation is straightforward: hand-tighten to proper torque spec and verify no leaks under load before extended operation.
