-3 Male to 1/2-20 Male Inverted Flare Fitting

The -3 Male to 1/2-20 Male Inverted Flare Fitting is a critical adapter for fuel and fluid system connections in high-performance marine engines and racing applications. Built by XRP-XTREME RACING PRODUCTS, this straight adapter bridges two incompatible hardline fitting sizes, allowing boaters and mechanics to integrate -3 AN male hose ends with 1/2-20 male inverted flare fuel lines. Whether you're upgrading a fuel delivery system, repairing damaged hardline connections, or fabricating a custom fuel or oil circuit, this fitting serves as the essential link that keeps fuel flowing reliably under pressure.

Manufactured from steel and finished with nickel plating, the -3 Male to 1/2-20 Male Inverted Flare Fitting resists corrosion in the salt-water and high-vibration marine environment while maintaining structural integrity under sustained fuel pressure. The inverted flare design on one end and AN male connection on the other create a leak-free seal when properly torqued into compatible ports; nickel plating protects against oxidation and extends service life in demanding conditions. At just 0.07 lbs, this compact adapter integrates seamlessly into tight engine compartments without adding unnecessary weight to your vessel.

Boaters running fuel-injected outboards, inboard gasoline engines, and high-performance racing boats benefit most from this fitting when connecting aftermarket fuel systems or replacing corroded factory hardline sections. Installation requires only a wrench and basic familiarity with AN and inverted flare standards; ensure your fluid system pressure rating exceeds the fitting's design limit, and always use thread sealant or PTFE tape on male threads for maximum leak prevention. This single fitting is essential inventory for marine mechanics, performance shops, and serious DIY boat owners stocking hardline adapter solutions for sale and repair work.
