137 Series Pipe Plug
Petersen Products 137 Series plumber / municipal test plugs are suitable for testing and temporary sealing pipes / fixtures during maintenance, repairs or installations. These small-diameter plugs are not supported by a cord, hence they provide excellent stretching and sealing characteristics in pipe diameters ranging from 20 to 305 mm. Selected models have a flow-thru bypass that allows fluid to pass through the plug while it is installed in a pipe. This functionality is used for applications, such as pressure testing, fluid sampling and flow control or diversion. These test plugs are made of NR / BR rubber, providing exceptional tensile strength, abrasion resistance and enhanced flexibility. They are designed to withstand a maximum temperature of 158 degrees F and are available in single or multi-size configuration.
