The extended-body version of the straight AN16 cutter style hose end. Its longer nipple moves the hose attachment further from the mating thread, buying spanner access and clearance where a large-bore hose would otherwise sit hard against a sump rail, tank boss or adjacent fitting. Function is unchanged from the standard end: the cutter slices into the hose liner as the socket draws up and grips it mechanically. AN16 handles dry sump scavenge and tank lines, coolant transfer, large breathers and fuel cell suction. For rubber-lined braided hose only. Measure the recess depth first, as the added length is a drawback where space is already tight.
