    • Ensures a long service life
    • Is resistant to chemical mixtures pH2 to pH12, fuels etc.
  • Coated with swelling material product group WO 22.2 QV-DBK
    • Ensures tightness up to 0.5 bar/ 5 m water column immediately on contact with water
    • Ensures tightness against gas diffusion (volatile halogenated hydrocarbons in soil air
    • Allows quick, easy removal (2 min). No adhesion! Makes damage-free removal possible 100 mbar)
  • The patented car tyre valve construction
    • Is simply inflated with compressed air (CO2-free!)
    • Makes on-site overpressure inflation technology simple
    • Allows flexible adaptation of the inflated cushion to fit the surrounding space and prevents buckling of cables and ducts or changes in technical transmission properties
    • Facilitates quick removal of air after cable retrofitting, by using accessory vacuum pump 33 VMSP or by changing the valve insert
    • Facilitates damage-free removal and re-installation


ADE/V sealing elements with a valve (Fibre Optics CT patent, registered under EP15154700.7), which were introduced with a petrolatum coating in January 2006 and redesigned with a swelling material coating (QADE/V-L) in 2013, have had undiminished success on the market.

The sealing element (valve) fulfils the requirements of the T-Com TS 0307/96 (Approval No. Wolf 2005-08-11 ADE 100 (valve)). Wolf sealing elements provide the user with a durable, reliable seal in a temperature range -15°C to +30°C (+45°C for a short period of 4h).

Sealing cushion materials:
  • The flat tube cushion is made of five-layered aluminium laminate.
  • The high quality of both material and processing guarantees a very low diffusion/leak rate of ~ 0.73 mbarl / year and ensures a long service life.
The filling unit:
  • In order to be able to fill the sealing cushion several times (4 times), a patented metal air valve with a plastic-coated valve extension is connected to the sealing cushion by means of a heat-seal welding process.
  • The pressure is filled via a pressure hose, which is plugged onto the sealing cushion to fill the car valve. After the pressure has been filled, the valve is sealed pressure-tight with the valve cap.
