A straight adapter combining an AN10 37-degree male flare with an M22*1.5 male metric thread. M22*1.5 is one of the larger common metric port threads, encountered on oil cooler housings, filter mounts, sump and gearbox bosses, and heavy-duty pump castings. Running it to -10 AN hose gives you a proven, serviceable connection that can be dismantled and reused, unlike crimped OE plumbing. This is a sensible choice for oil cooler feeds, transmission cooler lines and dry sump routing. Note that the -10 AN flare, not the M22 thread, sets the effective bore of the joint, and that the metric end seals on its washer or O-ring rather than on tape.
