Oetiker clamps are ideal for clamping rubber oil hoses because they maintain clamping force through heat cycles better than worm-drive hose clamps.

Standard worm-drive clamps can't expand as the hose assembly heats up and, therefore, force the hose material to extrude away from the clamp area during a heat cycle. After just a few heat cycles, they can lose most of their clamping force. Retightening the clamps simply starts the process over. Oetiker clamps can expand with heat and spring back when things cool off. They do not need to be checked or retightened, so the connection is maintenance-free. Sold individually.

Tip: For leak-free connections in high-pressure installations, install two clamps with the crimping ears clocked 90 degrees to each other.

Note: The recommended hose sizes in the table above apply to our textile-reinforced hose with our barbed fittings. All other installations require you to measure the OD of your hose after it is installed on the barb. You may need to order one size smaller than our table indicates.

Use our Dual Jaw Oetiker Clamp Crimp Tool (Part No. 3295-99, sold separately) to tighten these clamps.
