Marketing InformationSafely and reliably test DWV (drain, waste, and vent) systems with the Test-Tite Natural Rubber Multi-Size Dual-Stage Long Pneumatic Test Plug. Available in a variety of sizes and suitable for use with many different piping materials, this pipe plug offers contractors a dependable option for testing and temporarily stopping the flow of pipelines. Designed to be used in a "Y" to block the flow from the main sewer line, this multi-size test plug inflates in the top portion first and seals in two different pipe sizes-the vertical pipe of the "Y" and the horizontal pipe out to the main sewer line. Its dual-stage construction allows users to release the test media back into the pipe before completely deflating and removing the plug. Flexible yet rugged, the Test-Tite Multi-Size Dual-Stage Long Pneumatic Test Plug is constructed from a durable natural rubber compound and can be reused for multiple jobs. It comes with a 24-inch chain and ring assembly attached to a molded inflation valve and also includes a 36-inch inflation hose.
