RRA/V Ring space sealing

Universal sealing system for special
requirements in the gas and watertight
sealing of annular spaces


Temperature range
-30°C to +45°C
(+70°C for a short period)

 

The RRA/V is a further development of the T-Com-approved ADE/V sealing system and the UA/V, suitable for applications with specially high temperature and sealing-diameter requirements.


To seal the service entry etc.,the sealing element is inserted into the duct 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.

 

Available for cable ducts etc. from Ø 100 to > 500 mm
