Female To Male Flare FEM-3 TO MALE-4

The Female To Male Flare FEM-3 TO MALE-4 adapter is a crucial hydraulic coupling designed for boaters and water enthusiasts who prioritize reliability in their fuel and fluid systems. This adapter is perfect for those running high-performance engines, upgrading fuel lines, or maintaining essential hydraulic connections.

Constructed by XRP-XTREME RACING PRODUCTS, this fitting bridges two different flare thread sizes, ensuring secure, leak-free connections. The FEM-3 (female 3/8" flare) inlet threads onto a female-threaded line or component, while the MALE-4 (male 1/4" flare) outlet connects to a male-threaded fitting or hose end. This configuration effectively prevents leaks caused by mismatched port sizes.

Ideal for anglers, boaters who service their own rigs, racing enthusiasts, and professional marine technicians, this adapter provides the precision and versatility needed for fuel system upgrades and retrofitting newer engines into older hulls. Its compact, lightweight design fits snugly in tight engine compartments without adding unnecessary bulk.
