The REDHORSE PERFORMANCE 4AN/JIC Straight O-Ring Port Plug Black is a vital component for hydraulic line management in performance automotive builds. It is designed for those who are serious about their custom fuel systems, cooling circuits, or power steering setups. This straight port plug effectively seals unused AN fittings to prevent fluid leakage at critical connection points.
Engineered to meet JIC (Joint Industry Council) and AN (Army-Navy) specifications, the 4AN port plug features an integrated o-ring seal, eliminating the need for additional tape or sealant compounds. The straight design allows for direct port closure, making it ideal for tight engine bay layouts. Constructed from black anodized aluminum, it resists corrosion from exposure to fuel, oil, and coolant while maintaining a professional appearance.
This plug is particularly useful for tuners and mechanics who need to cap off fuel rails, transmission cooler lines, or turbo feed circuits during system modifications or testing. It is also valuable when switching between carbureted and fuel-injected engines, ensuring a reliable seal during transitions.
