Mikalor Worm drive hose clamp 70-90mm/12mm Constant Tension W3

The Constant Tension worm-drive hose clamps are designed to be used primarily in the automotive sector. The main advantage of this hose clamp over the standard Mikalor worm drive is to be found in the spring-loaded insert, fitted on a semi-circular support to the inside of the band.

The use of this spring-loaded insert guarantees constant pressure around the hose and the optimum performance of the hose clamp in case of variations in temperature, pressure or vibration. For this reason, constant tension worm-drive clamps are used mainly with tubes or hoses carrying hot air or on engine cooling systems, since clamps used in these applications are subject to expansion and contraction due to frequent changes in temperature. These hose clamps are manufactured entirely from stainless steel, thereby ensuring good corrosion resistance.

The complete range complies fully with the Directive EU 20032/95/EC.

(*) It is recommended to apply up to 75% of the maximum values contained in the table.
(**) The maximum application pressure can vary depending on the type of hose used and the geometry of the coupling.

Important! To choose correct clamp size, control that the hose outer diameter is within the clamping range specified in table.
