The stop-off device is mainly used to block high pressure gas pipelines, thereby the gas emission is limited to the maximum capacity of the sluice. The HA type safely blocks house connections up to 3".
We offer the stop-off device with or without primary pressure measurement, so there's no need for a another temporarily suppressor.
In the course of compability of units the stop-off device is based on the concept of using an existing städtler + beck pipe drilling device to grout purpose-built plugs. The special qualities of the chosen rubber compound give a guarantee for an extraordinary gas sealing, a tight hub of the plug inside the pipe and an extreme resistivity.
So their durability and particularly their reliabilty are quite higher.
The plugs can easily be fitted with the milling cutter and plug adapter, and after being drilled they can be grouted. The ability to rewarp them is most important, which afterwards allows a troublefree traction.
