A full 180-degree end for AN10 PTFE hose, used where a cooler, dry sump or high-volume fuel line has to leave its port and head straight back the other way. At this diameter the hose simply cannot make that turn on its own, so the fitting does it instead and the hose leaves in a gentle sweep. The olive-and-nipple seal is shared with the rest of the PTFE range and allows the end to be rebuilt with a new olive. Support the hose close to the fitting, since a large assembly hanging off the joint puts constant load on it, and set the clocking before assembly.
