Pipe sealing cushions and shut-off plugs
For shut-off of sewers, pipelines and drainage inlets. Sewers can be temporarily sealed with pipe stoppers to inspect, renovate or clean sewers and manholes.
Pipe cushions and shut-off plugs also play an important role in emergency situations, for example when contaminated wastewater or rainwater must be prevented from flowing on after accidents in order to prevent environmental damage.
Pipe stoppers are also used for leak tests according to DIN EN 1610. Here, a section of sewer is tested for leaks with air or water. EPUTEC offers not only sealing cushions suitable for shutting off, but also special test pipe sealing cushions suitable for leak testing of renovated and newly laid sewers and pipelines.
Our sealing cushions & shut-off plugs are made of expandable material (except for the conical pipe sealing cushions) and can be filled with liquid or air.
Premium Blocking Plugs
The premium Cherne i2-Series Blocking Plugs are particularly robust and durable. Premium components such as Nitto quality fittings and aluminium end plates ensure maximum stability and durability. The short, lightweight design makes these pipe plugs easy to transport and install, even in confined spaces.
The rubber body of the Cherne i2 is made of tear-resistant natural rubber. It is equipped with mechanically connected aluminium end plates, which minimises rust and corrosion. The 20 mm eyebolts used provide additional holding power. Our flexible Cherne premium blocking plugs are available in a variety of dimensions from 100 – 1500 mm.
