LF3003 Series Dielectric Unions

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.
