Kleiss MCS7-2PVC System Overview

Kleiss MCS7-2PVC System Overview

The Kleiss inflatable stopping systems meet the needs of the North 

American Natural Gas LDCs by providing a flow control system that is 

easy to use and effective at stopping off flow in various pipe materials 

and a wide range of pipe diameters.

The Kleiss MCS7-2PVC System consists of four major components: 

1) fitting to access the pipe, 2) tapping / completion tool, 3) inflatable stopper, and 4) stopping tool.

The Kleiss MCS7-2PVC System (all tools) has a maximum operating pressure of 7.5 psi. The inflatable stoppers have a 

design safety factor of 3. The balance of the tools have a design safety factor of 2.5.

The Kleiss MCS7-2PVC System is designed to handle flow control on pipe sizes up to 2” on PVC pipe. See Section 4.0 to 

identify and install the correct components before operating the equipment.

When working on non-metallic pipe materials, make sure the equipment is grounded per your company operating practices.

(Kleiss & Co., who developed the system, has reviewed and approved this manual.)
