Marketing InformationSafely and reliably test DWV (drain, waste and vent) systems with the Test-Tite natural rubber single-size standard pneumatic test plug with pressure relief valve. This standard test plug is designed to conform to irregular pipe shapes to create an effective seal. It offers contractors a dependable option for testing and temporarily stopping the flow of pipelines thanks to its compatibility with most pipe materials. A pressure relief valve reduces the risk associated with over inflation by releasing excess pressure into the atmosphere, so the plug doesn't rupture in the pipe. Flexible yet rugged, the Test-Tite single-size standard pneumatic test plug is constructed from a durable natural rubber compound, allowing it to be reused for multiple jobs. Models for 8 in NPS and larger feature an eyebolt for tethering, while models for 5 and 6 in NPS have a 12 in chain and ring assembly.
