Watts 0009866 Dielectric Union 1"FPT x 1"SW

The Watts 0009866 Dielectric Union LF3001A-1 1”FPT x 1”SW is a necessary component in HVAC systems because it provides electrical separation between various parts of piping. It avoids galvanic corrosion in which dissimilar metals in contact with the plumbing system results in the degradation of one or both of the metals. This union effectively stops the flow of random electrical currents that lead to corrosion and increases the lifetime of HVAC equipment. It has a 1” Female Pipe Thread x 1” Sweat coupling which makes it convenient to install. The integration of this union in the HVAC system improves its longevity, cuts on maintenance expenses and provides efficiency.
