45-degree push-on hose end in AN12 (-12), pushing straight onto socketless hose and gripping the barb without a clamp or crimped socket. AN12 is large-bore territory: oil cooler circuits, dry-sump scavenge, coolant and radiator plumbing, fuel cell venting and big breather runs on serious race engines. Forty-five degrees is the most-used angle on any build, steering hose around brackets, rails and pulleys while keeping the bend radius easy. Support long AN12 runs with P-clips, as the weight of assembled hose will work a loose line over time. Intended for push-on hose only, not braided hose built for a two-piece compression end.
