From the day we entered the water heater market in the 1950s through today, Perfection has been designing and building components for water heaters. This process began with a brass-plated fitting introduced in the late '50s to reduce corrosion, which was followed by a plastic-lined fitting providing the same benefits at a lower cost. We're proud of the fact that if you purchase a water heater in the U.S. or Canada it will probably contain Perfection components
