Endura Inverted Flare #3 to 3/8-24

The Endura Inverted Flare #3 to 3/8-24 by Russell is a precision hydraulic hose fitting designed for high-pressure brake and fuel line applications in automotive systems. This adapter is essential for mechanics and performance builders who require reliable, leak-free connections in demanding engine compartment environments.

The inverted flare design creates a metal-to-metal seal that effectively withstands thermal cycling and vibration, providing advantages over standard compression fittings. Constructed to Russell's durability standards, this fitting converts a #3 inverted flare line to a 3/8-24 thread size, facilitating seamless integration with modern fuel rails and brake distribution blocks.

Ideal for custom fuel system builds and brake line repairs, this fitting is particularly useful in retrofit applications where OEM hardline configurations need to transition to adapter-based layouts. Proper installation requires the use of flaring tools and careful torque control to ensure a secure seal without damaging the flare seat.
