Mishimoto AN Male / Female Adapters

Mishimoto’s AN fittings here are mostly hose ends, the fittings that go on the end of a hose, rather than port adapters. They come in families for different kinds of hose, so start by knowing which hose you are running.

Push-lock fittings are for push-lock hose: the hose is pushed over a barbed end and holds without a separate socket. They are listed straight and at 45, 90, 120 and 180 degrees, from -4AN to -12AN. Braided-line fittings are the threaded, two-piece type for braided hose, with a socket that grips the braid, and a 6AN version is made for PTFE-lined hose, which needs its own fitting.

Most of the rest are converters: ORB and M16x1.5 threads to plain hose barbs for coolant and breather lines, and an aluminium reducer from 4AN to 6AN. There is also a 3/4-inch one-way check valve.

Choose the hose and its fittings together, since a push-lock fitting will not seal on braided hose and a braided-line fitting will not suit push-lock hose. Size everything by AN number, check the angle needed at each end, and assemble braided fittings with a little oil on the threads.
