Russell Performance BLUE ANODIZED -6 TUBE COUPLING NUT W/ FLARED REDUCER TO -4 AN MALE

This Russell Performance fitting is a reducer, designed to connect a -6AN tube coupling nut with a flared reducer to a -4AN male fitting. It's made from 6061-T6 aluminum, which keeps it lightweight while still being strong enough for high-pressure applications. The blue anodized finish not only looks good but also helps protect the aluminum.

You'll find these fittings are precision machined to ensure a positive seal, even at maximum operating pressures. This is important for fuel or oil systems where a leak could cause serious problems. Russell offers a variety of adapter fittings to connect AN hose ends and hardlines to many different components, and this particular one helps bridge the gap between -6AN and -4AN sizes.
