Russell Performance -4 AN Flare Union (Black)

Russell is known for making reliable hose and fitting components for performance applications. This -4 AN Flare Union adapter fitting is a good example of their approach. It's designed to connect two AN-style hoses or hardlines together, making it useful when you need to extend a line or join two sections of hose in your fuel, oil, or vacuum system.

This particular fitting is precision machined from 6061-T6 aluminum, which keeps it lightweight. The black anodized finish not only looks sharp but also helps protect the aluminum. It's built to maintain a positive seal even at maximum operating pressures, so you can trust it to hold up under demanding conditions.
