Oetiker Hose Clamp 13-15mm 1pc

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.
Assembly 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 assembly
