OETIKER - Single Ear Insert Clamps
Oetiker Single Ear Clamp
OETIKER Single Ear Clamps with Insert (Product Group 154)

Suggested Alternative Clamps: Stepless Ear Clamps (Product Group 167)

OETIKER 1-Ear Clamps with Insert are ideal for critical joints that incorporate soft or hard rubber, or plastic materials.

The thin-walled insert incorporates an oval, deep drawn protrusion situated within the ear cavity to ensure that the insert maintains its circular profile while preventing the hose material from extruding into the ear. The prevention of this condition is critical when compressing soft materials. The double dimple combination ensures permanent all-round sealing.

This type of clamp is especially suited for use in the automotive industry, medical technology and with electrical and electronic components.

OETIKER System - the ear with the integrated dimple. This concept ensures that the geometry of the closed ear remains as low as possible, in addition to maintaining the effective clamping force. The closed ear geometry provides an inherent spring action in the clamp, permitting expansion and contraction during thermo cycling conditions without excessive loss in retention.

This type of clamp combines the geometry and properties of the 1-Ear Clamp with an additional insert made of stainless steel to DIN 1.4310 or UNS S30100.


Number 1  Deformation of ear provides visual indication that clamp is closed.

Number 2  OETIKER System: (ear with a dimple): Provides inherent spring action in the clamp, permitting expansion and contraction during thermo cycling conditions without excessive loss in retention.

Number 3  For small diameters as low as 2.9mm.

Number 4  Smooth de-burred edges prevent damage to clamped parts.

Number 5  Curled insert bridges the gap below the clamp ear and thus provides an effective all-round seal.
