Galvanized Steel to Copper Union With a Plastic Quick Connect Fitting
I have a Watts (SeaTech) WaterPex 3/4" CTS x 3/4 MPT plastic fitting. Can this be used in place of a dielectric union between galvanized steel & copper? The 3/4" MPT side would screw into a steel female thread, and the other side would accept 3/4" copper pipe (quick connect). Since the fitting is plastic, and the two dissimilar metals don't touch, isn't this a defacto dielectric union?
