The QAK/V is a further development of the T-Com-approved ADE/V sealing system, suitable for applications with specially demanding temperature requirements.

The sealing element is inserted into the cable channel or service entry etc. and inflated up to the pressure given in WO 05-3 via the tyre valve. Inflation is with air (CO2-neutral) and therefore environmentally friendly.

On inflation, the sealing element expands to fill the area to be sealed. The element can be removed by simply deflating it via the valve.

Specially developed materials prevent permanent adhesion of the element to its surroundings, guaranteeing fast, easy removal.
