What sets these hose clamps apart is the integral bridge that steps over the tubing's helical reinforcement. The clamp band registers only in the web, fastening securely to provide a true seal. This eliminates sudden hose detachment and reduces pressure loss from leakage. Simple, but effective.
The clamps are offered in two orientations to accommodate hose with a right-hand (RH) or left-hand (LH) spiral. Right-hand and left-hand hose spirals are akin to right-hand (standard) and left-hand screw threads.
Hose must have a minimum of 1/2" between coils.
