6 Inch PVC Sewer & Drain Flush Plug Fitting

6 Inch PVC Sewer & Drain Flush Plug Fitting for SDR-35 S&D Pipe, Threaded. A plug is a plumbing fitting that allows you to plug or end a section of pipe. This plug has a nominal measurement of 6 inch along with a flush top design. It has a male threaded connection, this means that it "screws" directly into the desired section of pipe. The fitting is specifically used in order to end a section of SRD-35 PVC pipe or fittings. These fittings are great for sewer and drain applications such stack vent (aka. stink stack, soil stack or stink pipe) and other drain applications within a residence or commercial property. However they should NEVER be used for gas or compressed air applications.
