Double ear clamps are widely used in maintenance and OEM medium pressure applications.
Their single piece construction assures a positive, tamperproof seal without damaging the hose or tubing
"Double ear" design permits compensations for tolerance variations in hose sizes.

For proper installation, select the nominal clamp size nearest to, but slightly larger than, the outside diameter of the hose or tubing to be clamped with the insert (fitting) in place.
One ear should be closed all the way. When the second ear is closed, the first ear will open slightly.
This creates a spring-like action which holds against pressure, vibration and hose shrinking caused by temperature changes or aging.
