#12 Str Fem Flare Swivel Coupling

The XRP #12 Straight Female Flare Swivel Coupling (Model 900112) is a precision hydraulic adapter designed for high-performance fuel, oil, and coolant line routing in marine engines, racing applications, and offshore powerboats. This 12 AN female-to-female straight coupling delivers the swivel connection reliability required when fuel lines, transmission coolers, and engine cooling systems demand zero-leak performance under sustained pressure and vibration.

Built from aluminum with blue and red anodized finish, this XRP-XTREME RACING PRODUCTS fitting resists salt-air corrosion that degrades standard steel adapters in marine environments. The swivel design accommodates minor misalignment and thermal expansion without inducing stress on connected hoses or hard lines, a critical detail when running high-flow fuel systems or multi-stage transmission coolers. Weighing just 0.19 lbs, the compact footprint (2.7 x 1.5 x 4.05 inches) fits tight engine compartments and bilge installations where space is already at a premium.

Offshore anglers upgrading to closed-loop cooling systems, weekend boaters replacing corroded fuel fittings, and performance builders installing auxiliary coolers all rely on this type of adapter to maintain system integrity under load. The 12 AN size handles flow rates appropriate for V8 and larger marine powerplants. Choose this coupling when you need a proven adapter that won't weep or fail at 80+ knots or under sustained high-RPM operation.

XRP-XTREME RACING PRODUCTS specializes in motorsports-grade hydraulic fittings. This adapter carries the brand's reputation for precision machining and consistent quality across racing fuel systems, aircraft plumbing, and marine propulsion. Whether you're doing routine maintenance or a full cooling system rebuild, this #12 straight female flare swivel coupling delivers the reliability serious boaters expect.
