Oetiker Double Ear Clamp
OETIKER 2-Ear Clamps (Product Group 101 & 151)

OETIKER 2 - Ear Clamps are multi purpose clamps for maintenance, repair and service purposes. With this type of clamp, rubber hoses, plastic tubing, electrical cables, air hoses and other materials can be securely fastened.

Compared to 1-Ear clamps, 2-Ear clamps are suitable for a wider diameter range Up to twice that of a 1-Ear Clamp - therefore, these clamps are more suitable for applications that contain thick wall hoses and require higher compression factors. The geometry of the closed ears increases the effective clamping force and provides a degree of elasticity to accommodate changes in size of the parts being joined, such as may be caused by thermal expansion or vibration. Please note for perfect sealing, it is essential that the ears are correctly closed during installation.

Number 1  2-Ear design for increased clamping range.

Number 2  Deformation of ears provides visual indication that clamp is closed.

Number 3  Robust design for reliable and good, permanent sealing.

Number 4  De-burred edges prevent damage to clamped parts.

Number 5  Fast, simple and secure installation.
