Watts 0881427 Gaskets

The Watts 0881427 (GB-C) is a professional-grade high-temperature gasket kit engineered for 1-inch dielectric unions, specifically the Watts 3001 and 3002 series. For contractors managing hydronic or steam systems, these EPDM gaskets provide a critical barrier against galvanic corrosion when joining dissimilar metals. Designed to handle the rigors of commercial piping, this dielectric union repair kit maintains seal integrity in steam applications up to 300°F (149°C) at a maximum pressure of 50 psi. The 1" GB-C kit is a standard requirement for technicians performing routine maintenance on hot water storage tanks and air conditioning units where thermal resistance is non-negotiable. Using Watts 0881427 gaskets ensures a positive seal that prevents leaks while isolating electrical currents between piping runs. Each kit contains two high-performance seals, providing the necessary components to restore full functionality to your union joints without replacing the entire assembly.

• Compatible with 1-inch Watts 3001 and 3002 Series dielectric unions.
• Constructed from high-temp EPDM for resilience in steam and hot water lines.
• Rated for service temperatures up to 300 degrees Fahrenheit to prevent thermal degradation.
• Critical for preventing galvanic corrosion and stray current transfer in mixed-metal piping.
• Lead-free construction compliant with modern potable water and commercial standards.

Is the Watts 0881427 compatible with other union brands?
These gaskets are specifically dimensioned for Watts 3001 and 3002 series 1-inch dielectric unions. Cross-compatibility with other manufacturers is not verified; check your union series before installation.

Can these gaskets be used in high-pressure steam systems?
While these are high-temp gaskets rated for 300°F, they are limited to a maximum working pressure of 50 psi. For high-pressure steam applications exceeding this limit, alternative sealing solutions are required.

What is the material composition of the GB-C gaskets?
The GB-C kit features EPDM (Ethylene Propylene Diene Monomer), selected for its superior resistance to heat, steam, and aging compared to standard Buna-N or neoprene seals.
