Tech Data Sheet: G465
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 D 4140 for continuous use at temperatures up to 110°C (230°F).
Test data/results and listings by Pittsburgh Testing Laboratory can be provided upon request. Contact a GRINNELL
Sales Representative.
