#3 Flare X 1/4in Npt Adapt.

The #3 Flare X 1/4in NPT Adapter (SKU XRP981634) is a precision straight fitting designed for anglers and boaters who demand reliability in their fluid delivery systems. Built by XRP-XTREME RACING PROD., this adapter bridges AN (Army-Navy) and NPT (National Pipe Thread) connections—critical transitions in marine fuel, coolant, and hydraulic lines where vibration and water exposure are constant threats. Whether you're running a performance outboard, upgrading your fuel system, or maintaining a custom inboard setup, this fitting ensures leak-free connections that withstand years of saltwater and freshwater abuse.

Engineered from aluminum and finished in durable blue anodized coating, the #3 Flare X 1/4in NPT Adapter provides corrosion resistance essential for marine environments while maintaining a lightweight profile that keeps your boat's weight distribution balanced. The straight configuration eliminates unnecessary bends, reducing turbulence and pressure loss in high-flow applications—a detail that matters when fuel delivery or hydraulic response time directly impacts performance and safety on the water. The 1/4 inch NPT male thread accepts standard pipe fittings, while the #3 AN male connection uses a flared seat design that creates a metal-to-metal seal without requiring thread sealant, making installation straightforward and maintenance-friendly.

This adapter is indispensable for marine builders, performance boat owners, and anyone converting or upgrading plumbing lines on inboard engines, jet drives, or auxiliary systems. It fits seamlessly into existing AN hose assemblies and NPT manifold ports, making it an ideal replacement or upgrade for aging brass fittings that may corrode in brackish or saltwater conditions. Weighing just 0.05 pounds and measuring 2.7 x 0.95 x 3.6 inches, the compact design fits tight engine compartments without adding bulk. For boaters who understand that a single failed fitting can end a season—or create a safety hazard—this XRP adapter delivers the corrosion resistance and pressure integrity that keeps you confident and on the water.
