For temporary or permanent plugging of 5/8" to 1-1/4" condenser and heat exchanger tubes, Conco's expanding tube plugs are tested to withstand a wide range of pressure, temperature and vibration conditions. The larger washer on the end of the EX-3 tube plug allows the plug to fit flush with the tubesheet and not be pulled into the tube by vacuum on the unit. Type EX-4 can be placed inside the tube at exact locations, to enable leak detection tests of other tubes. Pressure ranges of these plugs varies from 240 psi to 375 psi. The EX-F plug offers a separate gripping and sealing design in one plug and seals to 500 psi.

• Cylinder material is chloroprene expanding to seal tube

These plugs are easily installed for emergency and temporary plugging of condenser and heat exchanger tubes. They expand when wet to effectively seal off the tube. Conco Type FP one-piece plugs will not damage tubesheets and can be used in temperatures up to 230º F.

The one-piece tapered design of the Type 1 Pin Plug fits specific tube sizes. The Type 2 Pin and Collar Plug features a two-piece design with matchingtapered pin and collar for a positive full-length seal.
