Technical Information: Stepless® ear clamps hold against pressure and vibration or material shrinkage due to temperature changes or aging. A built-in spring action permits the clamp to breathe without loosening. When installing Stepless® ear type clamps over an object, please note that each ear must be crimped closed to obtain a proper seal. • once installed and clamped, any tampering is easily visible • Clamps are not reusable; they should not be pried open, doing so renders the clamps nonfunctional. • When ordering Stepless® ear clamps, select the nominal size nearest to, but always larger than, the outside diameter of the material to be clamped. The outside diameter should be determined with connection fully assembled.
