A 90-degree female flare swivel adapter in AN8. At this size, hose has a large minimum bend radius, so trying to turn a corner with the hose alone either kinks it or demands far more space than is available. The elbow makes the turn at the fitting, keeping the run compact and the flow path clean. The swivel joint then allows the outlet to be aimed anywhere through 360 degrees once the flare is seated, which is invaluable on fuel pumps, filters and oil cooler take-offs mounted in awkward positions. Both connections use the 37-degree AN flare seat, so confirm your mating components are true AN and not a 45-degree flare.
