What is StepLess Technology?

Oetiker invented the StepLess ear clamp in 1979. The ear clamp’s special design eliminates steps and/or overlaps on the inner circumference of the clamp for a 360° leak-free seal. Because the tongue resides in a groove, the “tongue-in-groove” feature exerts pressure on the assembled parts over 360°, enabling the clamp to apply a continuous radial force completely around the connection’s diameter.

Mechanical interlock

The interlock is a mechanical system for joining the clamp ends to permit closure. Some interlock designs can be opened for radial installation prior to closure.

Clamp diameter

The following applies as a guideline: To determine the correct clamp diameter, push the hose onto the attaching material, (e.g. the nipple), and then measure the outer diameter of the hose. The value of the outer diameter must be slightly above the average value of the diameter range of the clamp to be selected. The listed size of the clamp denotes the inner diameter (id) of the clamp.

How to Install

These clamps can be easily installed using Oetiker Hand Installation Pincers (HIP). The HIP tools have been designed especially for pinching ear clamps quickly and easily.
