Marketing InformationThe TEST-TITE® natural rubber multi-size pneumatic front air test plug offers contractors a versatile option for testing DWV (drain, waste and vent) systems. Designed for two or more pipe sizes and suitable for use with many different piping materials, this pipe plug can be used individually or in tandem with a back air test plug for DWV testing. Plug models for 12 to 24 in NPS and smaller include a pressure relief valve that 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® multi-size pneumatic front air test plug is constructed from a durable natural rubber compound and can be reused for multiple jobs. Each front air test plug comes with eyebolts on each end that allow it to be directly connected to another air test plug or to fasten a rope or inflation/lift line.
