30-degree push-on hose end in AN6 (-6), pushing straight onto socketless hose and gripping the barb without a clamp or crimped socket. AN6 is the everyday size: carburettor fuel feed, EFI returns, coolant overflow and header-tank runs, PCV and light oil plumbing on most street and club-level builds. 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. It offers enough bore for typical fuel and coolant duty without the bulk of the larger sizes. Fit it to hose made for push-on use and seat the hose fully against the fitting shoulder.
