Norma constant tension hose clamps CHC3045

Spring loaded to prevent weepage under the hose

Constant tension worm drive hose clamps overcome cold leaks often experienced when new hoses are fitted.
The radially positioned spring assures a continuous, self-acting tightening effect. This is the only clamp to use for sealing new hoses and hoses which are exposed to wide swings in temperature or have a tendency to flow under the pressure of the clamp. Rolled edges prevent the clamp from cutting into the hose. No leaks from these high performance clamps.
As supplied with our custom radiator kits. Suit SR & L series hoses, fits 30 to 45mm diameter hoses.
