I use these in 3/4 inch size when installing water heaters. Seem to be well made and the different metal surfaces are kept isolated from each other by plastic and rubber pieces.
Dielectric Union Review
from Corpus Christi, texas
This product-dielectric union was of quality construction at a very attractive price.
Proven product, often overlooked
from Catskills, NY State
I use die electric unions on piping jobs where there is a change from black/carbon steel pipe to copper or brass, and in coming off hot water boilers and hot water heaters. All too often, the galvanic action between dis-similar metals is overlooked, especially in residential piping. The Watts Dielectric unions make a good job, easy to fit up, disassemble so nothing gets scorched when sweating the brass end to the copper piping. Make up leak free, no ground seat to "take a set" and leak if not put back in the same place each time the union is broken apart and remade. Well made, good materials and machine work. Looks like Made In USA, no word to the contrary on Watts' packaging. I hope this is the case.
Quality product at a great price!
from Winthrop, Maine
I install these dielectric unions on all water heater installations. They also serve as the required union so service is always fast and easy with these installed.
By Ted the remodeler
from Los Alamos, NM
This product is well build and solid. I used one for my old boiler and it has worked well for 20+ years. I am adding two new zones and am reworking the manifold and am getting an new union even though the previous one was still in good shape.
