A one-piece cutter-style hose end in AN10 with a 120-degree bend. The socket and nipple form a single assembly, so building a hose means cutting the braid square, pushing it fully onto the nipple and tightening the socket down to swage the joint. The 120-degree angle turns the hose well beyond a right angle, which is exactly what you want when a port points the wrong way and a 90 would leave the line hard against a chassis rail or casting. AN10 is a high-flow size, used for oil cooler and scavenge lines, turbo drains and large fuel feeds, where forcing a tight bend into the hose itself would restrict flow.
