Oetiker® 1-Ear Clamps are used in places where clamping a second ear is impractical, or where a quick, repeatable and compact assembly is important in conjunction with a small clamping range. These clamps have a smooth inner band surface, protecting the hose or bundle from damaged caused by pulsation, expansion or contraction.

1-Ear Clamps are suitable for use by OEMs, but are also ideal for maintenance, repair and service purposes. With this design of clamp, rubber hoses, plastic tubing, electrical cables, welding hoses, and numerous other materials can be rapidly and securely fastened.
