Multiple Engagement Positions: Allows the clamp to be adjusted across various nominal diameters for greater flexibility.
Radially Guided Inner Ring: Ensures effective, uniform sealing performance around the entire circumference.
Clamp Ear Feature: Enables quick and easy installation, with visible deformation confirming a secure closure.
Precision-Formed Strip Edges: Minimizes the risk of damage to surrounding components during clamping.

FEATURES

Clamp ear (closing element)

Using tools designed by Oetiker, the clamp is closed by drawing together the lower radii of the “ear”. The maximum diameter reduction is proportional to the open “ear” width (s). The theoretical maximum reduction in diameter is given by the formula:

Max. diameter reduction = Ear width (s) / π

Multi-position interlock

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.
