A straight adapter joining an AN6 37-degree male flare to an M10*1.00 male metric thread. The 1.00mm pitch is the fine M10 thread and is a different fitting to M10*1.25 or M10*1.5, so verify the port pitch before ordering; the wrong pitch will start by hand and then ruin the thread. M10*1.00 appears on turbo oil feed bosses, metric hydraulic components and small sender positions. On the AN side, -6 is generous relative to the M10 port, so the metric thread sets the effective bore. The 37-degree flare seals dry on metal contact, while the metric end seals on the washer or O-ring the port was designed for.
