Universal sealing system for cable ducts and service entries in buildings in the telecommunication sector, for cable duct diameters 35-300 mm




The Swelling Sealing Bag (Fibre Optics CT Patent No. EP16177469) is a further development of the sealing cushion/valve (Fibre Optics CT Patent EP 15 154700.7), which has been deployed very successfully since 2006.

The valve sealing system and Swelling Sealing Bag both fulfil the requirements of Deutsche Telekom, T-Com TS 0307/96.

The leak rate (diffusion rate) of the Wolf sealing elements is far less than that demanded by Deutsche Telekom and far less than the leak rate of competitor products. Wolf sealing elements provide the user with a durable, reliable seal.

The Swelling Sealing Bag is available in two versions: as a disposable product or as a product that can be reused once. Another available alternative: Wolf sealing elements with a valve that can be inflated four times in total.

The new Swelling Sealing Bag is exclusively available to framework contract customers, in order volumes of 25.000 items p.a.
