WATTS Dielectric Unions

Watts LF3004 Series dielectric unions are used in commercial and industrial applications to prevent accelerated corrosion and deterioration in piping systems caused by galvanic and stray currents. They are installed between pipes made from dissimilar metals. These dielectric unions feature steel / iron / galvanised malleable iron / malleable iron & galvanised steel construction for structural rigidity and long service life. They have polysulfone insulation to prevent electrical hazards during operations and come with Buna-N gaskets for secure & reliable sealing between the pipes.

Watts LF3003 Series dielectric unions are installed at the junction of pipes with varying metal compositions, such as water heaters or pumps, to isolate the metals and reduce potential corrosion caused by electrolysis. These unions effectively maintain water quality and extend the lifespan of plumbing systems by preventing leaks and deterioration due to the chemical reactions caused by metal interaction. The brand's LF3003 Series dielectric unions safeguard water distribution systems, ensuring reliability and durability. They come with a comprehensive assembly consisting of a union nut, two tailpieces and a gasket. This combination creates a robust barrier against electric currents, effectively preventing galvanic corrosion. They have a design with a female iron pipe thread to female brass pipe thread connection, facilitating seamless integration and secure attachment between different types of pipes. These dielectric unions have Buna-N gasket, preventing leakage.
