• Create a dielectric waterway by insulating the inside of the metal casing, thus inhibiting the internal formation of galvanic local cell corrosion between the dissimilar metals in the presence of water
• Essentially eliminating galvanic local cell and stray current problems
• Clearflow dielectric waterway fittings continuously provide the most effective corrosion protection possible in any waterway system connection
• Inert, non-corrosive thermoplastic lining
• High temperature stabilized polyolefin polymer liner
