Figure 407GT Dielectric Waterway
Clearflow* Fittings protect plumbing systems through an innovative steel-to- plastic design that establishes a dielectric waterway . The dielectric fittings separate dissimilar metals in the electrolyte (waterway), eliminating the local galvanic cell .
The Clearflow Fittings metal-to-metal joint design maintains external electrical continuity, thereby preventing stray current corrosion . This feature is critical when stray current is present due to intentional or non-intentional grounding of direct current (DC) sources, such as phone systems and appliances .
Fittings meet the requirements of ASTM F 492 for continuous use at temperatures up to 110°C (230°F) .
