Heat Exchanger Test Plugs

Our Hepco heat exchanger or condenser test plugs are economical for the purpose of tube testing and will outperform all other similar black neoprene plugs due to their flexible nature. The silicone will allow for maximum inside tube flexibility through temperatures, solutions and cycling.

These are available as a wing nut hand tighten version or a jam nut wrench tighten version if they need to be inserted further into the condenser or heat exchanger tube.

• For temporary tube testing purposes.
• Effectively seals off tubes for Helium Leak testing as well as other testing.
• Easy to install and extract after testing is complete.
• Can be re-used for multiple heat exchangers and condensers.
• Comes in multiple sizes.
