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.
