90-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 right-angle body lets hose leave a port and turn immediately, which is what a firewall, bulkhead, tank face or block clearance problem calls for. Support long AN12 runs with P-clips, as the weight of assembled hose will work a loose line over time. Ordinary rubber hose will not grip the barb correctly, so use hose specified for push-on ends.
