45-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. Forty-five degrees is the most-used angle on any build, steering hose around brackets, rails and pulleys while keeping the bend radius easy. Hose is noticeably stiffer at this size, so plan the route before assembly rather than forcing it into place afterwards. Fit it to hose made for push-on use and seat the hose fully against the fitting shoulder.
