Genuine Oetiker Clamps
The interlock consists of one or two load-retaining hooks that withstand tensile loading during closure and a lock tab designed to hold the hooks in their windows prior to closure. With both designs the interlock can be engaged in several positions within the published range. This feature allows a single part to cover a range of diameters.
Adjustable Clamps with radial guiding (self-aligning design)
A tab formed on the inner portion of the clamp locates in a slot in the outer band surface. During assembly and closure, the tab slides in the slot and so avoids any step around the inner circumference of the clamp.
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.
