Water Heater Products

From the day we entered the water heater market in the 1950s through today, Elster 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 Elster Perfection components.


ClearFlow® Dielectric Waterway Fittings
ClearFlow® fittings protect plumbing systems through an exclusive steel-to-plastic design that establishes an effective dielectric waterway. They feature thermoplastic-lined steel construction to reduce the local galvanic cell corrosion which normally occurs when dissimilar metals are connected in the presence of water.

In addition, the metal-to-metal joint design of this fitting maintains external electrical continuity, preventing stray current corrosion. ClearFlow® fittings are designed for continuous use at temperatures up to 225°F (±5°F) and for pressures up to 300 psi.

PlastiSert® Fittings
PlastiSert® Fittings provide a smooth, self-cleaning, always sanitary waterway. The NSF/FDA listed, chemically inert, non-corrosive thermoplastic lining is held permanently in place by our unique design construction. The zinc-plated steel outer casing provides strength and thread support. PlastiSert® fittings are also available with formed end (FE) liners.
