-20m To -16m Flare Rdcr

The XRP-XTREME RACING PROD. -20m To -16m Flare Reducer is a straight-through aluminum adapter fitting designed to connect larger -20 AN male hose fittings to smaller -16 AN male ports. Built from lightweight aluminum with blue anodized finish, this reducer maintains structural integrity while resisting corrosion in harsh marine and engine bay environments. It serves as a critical step-down fitting for high-pressure fuel and fluid systems where direct size transition is required.

The straight-through geometry eliminates flow restrictions at the connection point, a key consideration in racing and high-performance marine applications where fuel delivery consistency directly impacts engine performance. The -20 to -16 AN size transition accommodates manifold fuel block configurations, return line setups, and custom plumbing where hose diameters must step down without compromise. Blue anodized aluminum provides both weight savings and superior corrosion resistance compared to bare aluminum—essential for saltwater boats and high-heat engine compartments where oxidation and galvanic degradation are constant concerns.

This adapter is engineered for serious boaters, marine mechanics, and performance technicians who demand precision component matching in fuel systems, cooling loops, and hydraulic circuits. Whether upgrading a high-output outboard fuel rail, reconfiguring a closed-loop cooling line, or fabricating a custom fuel delivery system, the XRP reducer provides a clean, leak-free interface without requiring hose barb adapters or multiple fittings. Its compact footprint (3.7 × 1.95 × 5.2 inches) and lightweight design (0.28 lbs) make it ideal for space-constrained engine bays and weight-conscious performance builds.

AN fittings remain the standard for high-reliability fluid systems in racing, marine propulsion, and aftermarket performance work. The -20 to -16 step-down is one of the most common transitions in modular fuel systems, making this single-unit adapter a reliable solution to eliminate fitting stacks and reduce leak points in your plumbing network.
