For temporary or permanent plugging of 5/8” to 1-1/4” condenser and heat exchanger tubes, Conco’s expanding EX-3 tube plug is tested to withstand a wide range of pressure, temperature and vibration conditions up to 150 PSI. The EX-3 features a large outer washer that allows the plug to fit flush with the tubesheet and not allow the plug to be pulled into the tube by the vacuum of the unit. For applications where you want to place a plug at the exact location inside the tube consider the EX-4 , and for applications where you desire enhanced sealing at higher pressures, consider the EX-F.
