Ear Clamp—A Small Clamp

Ear Clamps consist of a band (usually stainless steel) into which one or more “ears” or closing elements have been formed.

The clamp is placed over the end of the hose or tube to be connected and when each ear is closed at the base of the ear with a special pincer tool, it permanently deforms, pulling the band, and causing the band to tighten around the hose. The size of clamp should be chosen such that the ear(s) are almost completely closed on installation.

Other features of this style of clamp include: narrow band widths, intended to provide a concentrated compression of the hose or tube; and tamper resistance, due to the permanent deformation of the clamp’s “ear”. If closure of the clamp “ear(s)” is performed to manufacturer’s recommendations, which generally provide for constant jaw force, the sealing effect is not unduly sensitive to component tolerance variations.

Some such clamps feature dimples intended to provide a spring effect when the diameter of the hose or tube contracts or expands due to thermal or mechanical effects.
