CAMCO DIELECTRIC NIPPLE - 2 PACKCamco dielectric nipples prevent galvanic corrosion at water heater connections by insulating dissimilar metals from each other. The thermoplastic-lined steel nipple stops the direct metal-to-metal contact between the water heater tank and copper or galvanized supply lines that causes accelerated corrosion and connection failure. Two nipples per card cover both hot and cold water heater connections.
