Kleiss MCS Systems and MDS Stoppers

In 1998, Kleiss & Co. developed an industry changing flow stopping system for the natural gas industry. This innovative system uses a revolutionary, patented Multi-Dimensional Safety (MDS) Stopper instead of the traditonal flow stopping methods. The MDS Stopper is a flexible, inflatable device which can stop off gas in multiple types of pipe material or wall thickness and various pipe diameters. This means that one system can be used in many applications no longer needing a unique system for each job.
