The 90-degree AN4 hose end is the go-to when a line has to leave a fitting at right angles — turbo oil feeds off a restrictor, gauge senders in a crowded bay, or a run that must drop straight down a chassis rail. Making the turn inside the fitting rather than in the hose protects the hose from kinking, which matters on the small AN4 bore. The swivelling nut means you can tighten the joint fully and still have the hose sitting where you routed it. Reusable two-piece construction for braided hose; check the elbow clears surrounding components before final assembly.
