Important for Warranty

Many water heater manufacturers state that their warranties are invalid unless heater tanks are insulated and isolated from copper tubing.

Stop Stray Currents!

Dielectric unions stop the flow of stray electrical currents which may be picked up from nearby electrical lines or appliance grounding connections.

Prevent Electrolytic & Galvanic Corrosion

Use Central's dielectric unions wherever there is a need to prevent electrolysis or galvanic corrosive action, i.e., when joining dissimilar metals in your piping and plumbing systems. These unions have numerous uses such as - for water heaters - for water storage tanks - for gas piping - for air conditioning - for water conditioners for water pumps - for steam lines - for plating tanks - for oil piping - for fan coil units - for cabinet heaters - and for finned tube radiation and convectors.

Stop Corrosion from Dissimilar Metals

When two dissimilar metals are joined together in the presence of water, an electric current is formed. Also the presence of heat can greatly accelerate the flow of electricity and speed up the galvanic corrosion process. Central's Dielectric Unions solve the problem!
