Dielectric Pipe Fittings, Unions and Bolt Insulators - 1

Series 3000 Dielectric Pipe Fittings, Unions, Bolt Insulators Description Series 3000 Dielectric Pipe Fittings and Unions are durable, corrosion resistant fittings and unions that consist of a union nut and two tailpieces. A gasket separates the two tailpieces preventing an electric current from passing. For flanged fittings (Models 3100, 3110, and 3200), a bolt insulator is required to insulate each bolt in the flange. Watts also offers bolt insulators in a range of sizes. Dielectric fittings/unions are designed to install between pipes made from dissimilar metals. They prevent accelerated corrosion and deterioration in the piping system due to galvanic and stray current. Features • Designed and manufactured to the highest quality standards. • Unions individually factory certified to withstand a minimum of 600 volts on a dry line with no flashover. • Unions rated to 180°F (82°C) at 250psi (17.2 bar). • Flanged fittings rated at 175psi (12.1 bar). • Standard Gasket A (GA) suitable for water, air, oil, natural gas, propane, gasoline, kerosene, mineral oil, vegetable oil, and alkalines in 180°F (82°C) at 250psi. Applications Dielectric fittings/unions are for use in residential, commercial, and industrial applications. Specific applications include the connections of piping of dissimilar metals on hot water storage tanks, water and air con- ditioners, processing tanks, steam, gas, and water piping. These fittings/unions prevent the flow of galvanic current (an electric current) and stray current (DC current) passing from one dissimilar metal to another. Galvanic current accelerates corrosion in the piping system leading to premature deterioration of the system. Stray current produces extraordinary anodes and cathodes that can inadvertently enter an alternate (but unintended) path and create corrosion in the piping system. Using dielectric fittings/unions prevents this type of corrosion from occurring. Note: For applications of gaskets other than specified above, contact your local authorized Watts representative. Materials Dielectric fittings/unions consist of one or more of the following materials used in accordance with American Society for Testing and Materials (ASTM): Gray iron Malleable iron parts Steel parts Brass parts Bronze parts Zinc Coatings Bolt insulators (required) Standard Gasket A Optional GB Gasket ASTM A48 ASTM A-197 ASTM A108 ASTM B-16 ASTM B-584 ASTM B633 Polysulfone Buna-N EPDM
