150-degree push-on hose end in AN10 (-10), pushing straight onto socketless hose and gripping the barb without a clamp or crimped socket. AN10 handles high-volume, low-pressure work: turbo and dry-sump drains, oil and gearbox cooler lines, generous breather and catch-can plumbing, and large-pump fuel returns. One hundred and fifty degrees is very nearly a reversal, and it answers a port pointing directly away from the run with no space to loop the hose by hand. Hose is noticeably stiffer at this size, so plan the route before assembly rather than forcing it into place afterwards. Ordinary rubber hose will not grip the barb correctly, so use hose specified for push-on ends.
