More About Oetiker Clamps and Hose Clamps
is a fastening device to hold or secure objects tightly together to prevent movement or separation through the application of inward pressure. There are many types of clamps
available for many different purposes. Some are temporary, as used to position components while fixing them together, others are intended to be semi-permanent and permanent.
Oetiker Tab/Ear Clamps consist of a band (usually stainless steel in our stock) 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 Oetiker pincer tool #14100387/14100386, it permanently forms around the tube and hose barb, pulling the band, and causing the band to tighten around the hose and fitting. The size of a clamp should be chosen by tubing Outside Diameter so that the ear(s)/tab(s) are almost completely closed on installation.
Other features of Oetiker clamps include: narrow band widths, intended to provide a concentrated compression of the hose/tube and fitting; and provide
some tamper resistance, from deformation of the clamp’s “ear”. Oetiker 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. Oetiker stepless clamp was invented by Hans Oetiker in Horgen, Switzerland, which eliminates steps or gaps on the inner circumference of the clamp. This is said to provide uniform compression and a 360° seal. Oetiker stepless clamps are well suited to applications involving thin-walled hoses, with higher retained loads. Oetiker Clamps are commonly used in the Automotive, Aviation, OHV, UTV, Marine, Beverage and Irrigation industries to name a few.
