A 45-degree AN4 hose end for the many situations where a straight fitting would force too tight a hose radius but a 90 is more turn than you need. The moderate bend eases the line away from a port and lets it run naturally, which helps small AN4 hose keep its bore open on oil feed and gauge lines. The AN4 nut swivels so the joint can be tightened without twisting the hose behind it. It is a reusable two-piece design intended for braided hose, so it can be moved to a fresh length later. Dry-fit the routing before you cut hose to length.
