Oetiker® 101 Series Double Ear Clamps

Oetiker® 101 Series Double Ear Clamps

Oetiker® 2-Ear Clamps
The ears of these clamps do not have a dimple and nearly double  the clamping range, compared to the 1-ear clamp. 2 ears provide a degree of elasticity to accommodate changes in size of the
parts being joined, such as that which may be caused by thermal expansion or vibration.

Installation techniques are similar to those for 1-Ear Clamps, but the force applied when closing the second ear may react against the opposing closed ear and make a second crimping operation
necessary. For perfect sealing, the ears must be adequately closed during installation.

Assembly recommendations
The ears of these clamps should be closed with the recommended, uniform force (known as force priority). This method will result in a constant, reproducible stress within the clamp material, without overloading either the clamp or the parts being assembled. The nominal diameter of the clamp should always be chosen so that, when installed with the correct clamping force, the ears are almost closed. Complete process monitoring and 100% process documentation are available using the “Electronically Controlled Pneumatic Power Tool” Oetiker ELK.

Selection: Measure the outside diameter (O.D.) of the hose to be clamped. Select a clamp with an average size range that is close to the hose’s O.D. An optimal clamp size will allow the hose’s O.D. to fall in the middle of the clamp’s size range.

Clamping Procedure: After assembling the hose, use an Oetiker® ear clamping tool to compress the clamp’s first ear, followed by clamping the second.  The clamp’s ears should be reduced in size by at least 40% to provide enough clamping force. If sized correctly, the clamp’s ears should not close completely during compression.
