Oetiker Parts & Accessories

Oetiker make the single-ear hose clamps fitted as original equipment on Harley-Davidson fuel and oil systems. Once compressed with the dedicated tool, they maintain constant clamping force through temperature cycling — expanding and contracting with the hose to keep the seal without ever needing re-tightening.

The aftermarket kits are selected specifically for two-wheeler fuel, oil, and coolant connections. If you're redoing hose connections properly rather than defaulting to worm-drive clamps, this is the professional approach.
