Stepless ear clamp. 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. Made of 304 stainless steel. Ensured clamping seal. For low durometer and/or thin-walled hose/tubing. Smooth inner band prevents damage to the hose while the tongue-in-groove design provides a 360 degree seal. No steps or gaps inside the clamp. Install clamps using 1098 or 1099 clamp tools.
