A dielectric union is a special adapter or fitting used in various metal pipe systems to isolate the connection of dissimilar metals. An elastomeric rubber gasket seals the connection, and a plastic composite material separates the copper tube connection from the dielectric union's hex nut. When different metals come into touch with each other, they begin to corrode. The little amount of acid in water initiates the electrolytic reaction between the two metals, causing electrons to flow from one metal to the other. This eventually leads to galvanic corrosion. To prevent this from happening, a dielectric union is employed to connect the two dissimilar metal pipes.

FAQS

What Is A Dielectric Union?

A-To prevent galvanic corrosion, two-part fittings of different metals that are electrically insulated from one another are referred to as dielectric unions. The phrase is frequently used to refer to a group of plumbing pipe fittings. Two distinct metals exposed to an acidic solution can experience galvanic corrosion. A current of electricity flows between the two metals as a result of this mixture, which functions as a battery.

When To Use Dielectric Union ?

A-In an electrolytic reaction, water serves as the electrolyte and occurs when two dissimilar metals come into contact. Corrosion then starts to occur in the metals. Galvanic corrosion is what this is. The pipes made of various metals are joined together using dielectric unions to avoid this happening. When there is poor water quality and galvanized materials have a high probability of corroding, brass is frequently utilized for fittings for copper pipes. Brass is sensitive to acidic water despite being rust-resistant.

How To Install Dielectric Union ?

A-Cover the threads of the steel pipe with many layers of pipe sealing tape. The steel pipe should be connected to the threaded end of the dielectric union body. A pipe wrench should be used to tighten the union as you turn it clockwise.

With the open threaded end facing out, slid the union nut over the end of the copper pipe. Additionally, the copper pipe must be covered by the orange plastic insulator as illustrated.

Install the copper solder adapter onto the copper pipe, then melt the copper solder adapter to the copper pipe with a propane flame. Try to keep the plastic insulator as far away from the torch as possible to prevent the melting the insulator.

Union nut and union body are put together by sliding the rubber gasket between them. You should clockwise-twist the union nut with a pipe wrench.

Lastly watertight connection should be checked.
