Corrosion is no match for BrassCrafts COPPER-FLEX water heater connectors. Constructed of seamless copper tubing, COPPER-FLEX water heater connectors are the professionals choice for water heater installations. Featuring an integrated dielectric sleeve, the sleeve isolates dissimilar metals within the waterway, where galvanic and electrolytic corrosion have their greatest potential. This separation provides complete protection against galvanic corrosion that can deteriorate the connector and cause leaks. In addition, the integrated dielectric sleeve eliminates the need to install an additional dielectric union, reducing time and installation costs.
