Fox Adapter 9/16-18 O-Ring Boss x -8 Male An Straight Steel

This straight steel adapter from Fox features a 9/16-18 O-ring boss fitting on one end and a -8 male AN fitting on the other. It's constructed from durable steel, making it a solid choice for connecting various fluid lines in your engine bay. The O-ring boss seal ensures a leak-free connection when properly seated, which is critical for maintaining proper fluid pressure and preventing contamination in your fuel or oil systems.

The straight design makes for a clean and simple routing of hoses or hard lines, avoiding unnecessary bends that could restrict flow or create stress points. This adapter is a common component when building custom fuel systems, oil cooler lines, or other fluid transfer setups where specific port sizes need to be adapted to standard AN fittings. Its steel construction offers good strength for typical automotive fluid pressures.
