About Us

In 1998, Kleiss & Co. developed an industry-changing flow stopping system for the natural gas industry. Sixteen years later, Mainline Control Systems (MCS) was formed to bring these unique systems to North America. In partnership with Kleiss, MCS stocks, supports, and distributes the Kleiss systems and provides education and training to the personnel operating them.

After looking through the site, if you don’t see something that meets your needs, check with us. We continually expand the depth of systems and tools offered.
