Description

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 ADVANTAGES Reliability •Total tightness •Extremely durable Safety •Safety •Highly wear-resistant Installation •Rapid installation DETAILED INFORMATION •Material: double layered 200 mm NPVC fabric on a polyester backing •Technique: hot vulcanization in a vacuum autoclave •Max. height. :200 mm •Inflation: by air •Temperature resistance: -25 to +85°C (please contact us for any use outside this temperature range) •Inflation pressure: max. 1 bar •Back-pressure: 0.1 bar •Supplied accessories: o1 x ¾’’ G quick connector for inflating the stopper o1 x ¼’’ G CEJN coupler for checking the pressure o1 x DN 20 Camlock adapter for pressurizing the pipe o4 hoisting rings.
