This 90-degree stainless hose end runs -3 braided line into a female AN4 connection, so it doubles as a size transition in a single fitting rather than needing a separate reducer in the joint. Fewer joints means fewer places to weep. It is a useful part when a component has been built with AN4 ports but the circuit only needs -3 line, which is common on brake and clutch conversions and on gauge feeds. The right-angle body suits ports that point straight at an obstruction. Machined from SUS303 stainless for corrosion resistance. Check that the mating male AN4 fitting’s seat form matches, and route the hose so the elbow is not carrying load.
