30-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. Thirty degrees is the gentlest correction available, for when a straight fitting just fouls a bracket but a 45 would swing the hose too far off line. 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.
