180-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. The 180-degree body sends hose straight back alongside itself, replacing a hand-formed U-bend that would otherwise kink or crowd nearby components. Support long AN12 runs with P-clips, as the weight of assembled hose will work a loose line over time. Push-on assemblies suit low-pressure lines, so keep them off pumped brake or clutch circuits.
