POP-A-PLUG® CPI/Perma Medium Pressure Tube Plugs
Permanent sealing solution for leaking heat exchanger, condenser and boiler tubes. Pop-A-Plug CPI/Perma Medium Pressure Tube Plugs feature internally and externally serrated sealing rings designed to maintain a helium leak-tight seal under extreme thermal and pressure cycling.
EST Group’s mechanical tube plugs install hydraulically in minutes with a unique engineered breakaway. Controlled installation force limits operator fatigue and prevents damage to the tube, tubsheet and surrounding tubes.
Pop-A-Plug Tube Plugs accommodate a broad range of tube sizes and materials, with full material traceability documentation available to support fossil, nuclear, refining, petrochemical and chemical industry requirements.
