Watts 0881426 Dielectric Gasket Kit

The Watts 0881426 Dielectric Gasket Kit is a critical component for maintaining the integrity of 3/4" dielectric union connections. This professional-grade GB-B replacement kit features EPDM (Ethylene Propylene Diene Monomer) construction, specifically engineered to withstand demanding environments. Designed for high-temperature steam applications, these gaskets maintain a reliable seal at temperatures up to 300°F (149°C), ensuring protection against pressure loss and fluid leaks in hydronic and steam systems. By providing electrical isolation between dissimilar metals, this kit effectively prevents galvanic corrosion, extending the service life of pipe fittings and system components. It is a direct OEM replacement for gaskets used in Watts Series 3001, 3005, and 3007 dielectric unions. This kit includes two precision-cut gaskets, allowing for a complete rebuild of the union faces to ensure a leak-resistant joint that meets lead-free requirements for potable water and commercial HVACR applications.

• High-Temperature Resistance: Performance-rated up to 300°F for use in residential and commercial steam systems.
• Material Integrity: EPDM gaskets provide superior resistance to corrosion, ozone, and heat aging.
• Galvanic Protection: Facilitates dielectric isolation to stop the transfer of electrical currents between copper and steel piping.
• Broad Compatibility: Replaces the GB-B gasket for 3/4" Series 3001, 3005, and 3007 unions, and 1/2" Series 3003, 3004, 3006, and 3008 unions.
• System Efficiency: Corrects surface irregularities to prevent refrigerant loss or pressure drops in condensate lines.

• What unions does the GB-B kit fit? This kit is specifically designed for 3/4" Watts dielectric unions (Series 3001, 3005, 3007) and certain 1/2" series (3003, 3004, 3006, 3008).
• Can these gaskets be used in steam lines? Yes, the high-temp EPDM material is rated for steam service up to 300 degrees Fahrenheit.
• Is this kit lead-free? Yes, the Watts 0881426 is compliant with lead-free regulations for use in potable water systems.
