Comments about Watts 3/4"" LF3003 FxF Dielectric Union, Lead Free:

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.

Proven product, often overlooked

By Steamhog

Comments about Watts 3/4"" LF3003 FxF Dielectric Union, Lead Free:

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.

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.

Solid product

Comments about Watts 3/4"" LF3003 FxF Dielectric Union, Lead Free:

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.

      A:

      The inside diameter of this union is 1/2". The outside diameter of the part at the union nut is 1-1/2"

  • Q:

    The specs for the product give the temperature rating as "180°F (82°C) with standard gasket A; 300ºF (149ºC) with optional gasket B" Does this part come with both gaskets, or must gasket B be ordered separately?

      I do not remember more than 1 gasket coming with the union. It has been long enough ago that I can't be sure.

  • Q:

    I would like to replace the majority of my galvanized piping in my home with pex. However, the galvanized water lines come into the house from the outside. Would this be the best option to transition from galvanized to a copper peice with a pex attatchment on it. Or is there an easier way? Can i just buy a Male or Female brass pex conversion fitting and screw onto the galvanized pipe?

      You can either use this or just get a PEX adapter.

      A:

      you should be able to purchase a fitting that will attach to the galvy (which is sized "IPS"... iron pipe size) and allow you to switch directly to pex. Just make sure that the female thread is not sized for "CTS"... copper tube size.
