OTR - Stoppers for inspection well testing
The OTR stoppers for inspection well testing are used to test the tightness of inspection wells that are found in waste-water systems. Inflatable OTR stoppers are particularly easy to install thanks to their lightweight and flexibility.
The stopper bladders are only 200 mm high, whatever the pipe’s diameter. This means that they can be used in a variety of narrow spaces.
And what is more, stoppers for inspection well testing are equipped with by-pass tubes. These are designed for the pressurization that is typically applied during inspection well testing.
