*Mechanical Plug Warning: Maximum head pressures that a pipe plug may hold back can only be estimated. Pressures are influenced by many factors including fluid and debris in the pipeline, type and condition of pipe, tightness of plug seal, and temperature. Plugs should always be inserted fully into pipeline and should be mechanically blocked when slippage may cause property damage or injury. NEVER use a test pressure greater than the capacity of the weakest pipe or component in the system. NEVER use a mechanical plug when its failure would cause injury.
