Elbow 90 X #10 Flare X 3/4 NPT

The Elbow 90 X #10 Flare X 3/4 NPT is a professional-grade hydraulic and fuel line adapter designed for high-performance marine engines, racing boats, and custom water-cooled systems where precision hose routing is critical. Built by XRP-XTREME RACING PRODUCTS, this 90-degree elbow fitting transitions between AN10 flared hose connections and NPT threaded ports—making it indispensable for anglers, boaters, and marine technicians who demand reliability under pressure. Whether you're plumbing a new cooling circuit, upgrading fuel delivery on a performance outboard, or rebuilding a marine engine bay, this adapter eliminates kinks and maximizes space in tight engine compartments.

Constructed from aircraft-grade aluminum and finished in durable blue anodizing, the Elbow 90 X #10 Flare X 3/4 NPT resists saltwater corrosion and handles the thermal cycling that comes with extended time on the water. The #10 AN male flare end accepts standard -10 hose with JIC flare swaging, while the 3/4-inch NPT male port threads directly into engine blocks, manifolds, or auxiliary equipment without adapters. The 90-degree geometry eliminates the need for complex routing and reduces stress concentrations in high-vibration marine environments—critical for maintaining tight seals and preventing weeping under sustained RPM and load.

This fitting suits custom cooling systems, fuel injection upgrades, bypass circuits, and hydraulic power steering installations on inboard and outboard engines. Boaters upgrading from stock cooling to heavy-duty marine radiators and anglers retrofitting high-output engines will find this adapter essential for clean, code-compliant plumbing that withstands years of saltwater and freshwater service. Installation is straightforward—hand-tighten the flare nut to avoid galling the aluminum, then torque the NPT port into the receiving cavity. Keep a spare on board for emergency repairs during extended offshore trips.
