This Hans Oetiker design was the first of its kind when it came onto the market in 1951 and, since then, it has revolutionized connection technology throughout the world. To this day, it has remained a best seller.
Oetiker 2-ear clamps are suitable for Original Equipment Manufacturing (OEM) amd Maintenance Repair Overhaul (MRO). These clamps are also suitable for use with rubber hoses, plastic tubing, electrical cables, welding hoses and other materials.
The 2-ear clamps, in comparison to the 1-ear clamps, have a larger clamping range. Due to the specific geometry of the closed ear, clamping force is increased and creates a spring effect when the hose material expands or contracts in response to thermal or mechanical influences such as temperature, vibration, etc.
For a perfect seal, the ear must be closed correctly at installation. |
