Pop-A-Plug® CPI/Perma Medium Pressure Tube Plugs

Perform Heat Exchanger Maintenance on Leaking Condenser and Boiler Tubes


Choosing the wrong plug for your heat exchanger tube leaks can increase downtime and further damage equipment.

EST Group’s Pop-A-Plug Tube Plugs are a permanent mechanical tube plugging solution for leaking heat exchanger, condenser, and boiler tubes. Mechanical tube plugs feature an internally and externally serrated ring designed to maintain a helium leak-tight seal even under extreme thermal and pressure cycling

Pop-A-Plug Tube Plugs install hydraulically in minutes with an engineered breakaway while offering a controlled installation force to limit operator fatigue and prevent damage to tubes, tubsheets, and surrounding tubes.

Choose from a broad range of tube sizes and materials. Full material traceability documentation available.
