General information: SSB2 swelling sealing bag

The Swelling Sealing Bag (Patent PCT/EP 2017 065542, EP 16177469) is a further develop-ment of the sealing cushion/valve (Fibre Optics CT Patent EP 15 154700.7), in use very successfully since 2006 and characterised by easy installation and removal as well as reusability. The Wolf Swelling Sealing Bag sealing fulfils the requirements of T-Com TS 0307/96.

The leak rate (diffusion rate) of the Wolf sealing elements is far less than that demanded by T-Com and far less than the leak rate of competitor products. Wolf sealing elements provide the user with a durable, reliable seal in a temperature range of -15 °C to +30 °C (4 h at 45°C for a short period).

The Swelling Sealing Bag has been developed as a product that can be reused once, in contrast to the Wolf valve sealing elements, which can be inflated 4 times in total.

The packaging units for Swelling Sealing Bags contain 100 units.

Product description:

Sealing cushion materials:
The flat tube cushion is made of a five-layered aluminium laminate.The high quality of both material and processing guaranteesa very low diffusion/leak rate
of ~0.73 mbarl/year and ensures a long service life.


The filling unit:
The plastic filling tube is welded to the flat tubular cushion by means ofa special heat-sealing process (patent applied for). The pressure filling is carried out via a filling adapter (19.1 SSB-A), which is attached to the filling tube before inflation. After inflation, the filling tube is pressure-sealed by means of a crimp sleeve and the original Wolf crimp tool.Type SSB2-L can be reused once (i.e. is inflatable twice in total).
