Die electric union

It is installed between pipes made from dissimilar metal. Each includes a union nut, tailpieces, and gasket. We offer dielectric unions in a range of configurations, sizes, and materials. The term is most commonly used to describe a family of plumbing pipe fittings. Use these unions to connect different metals in a piping or plumbing system.

Unions separate into three pieces for access to your line. Galvanic corrosion occurs where two different metals are exposed to an acidic solution. Use them for connections that must be electrically insulated.

Is brass an alternative to dielectric union? What is dielectric union plumbing? They have a plastic sleeve that inhibits destructive corrosion. Is dielectric union necessary?

The installation of a dielectric union to separate the two dissimilar metals will prevent corrosion that would otherwise occur over time. Thanks for the interesting questin, Jesus: The answer is no. The Union design and thermo-baked epoxy polymer coating provides insulation against galvanic corrosion and current flow eliminating any stray corrosion.

This union is made from galvanized steel and lead-free brass. A dielectric union is utilized in a plumbing system to make a connection between two pipes of dissimilar metal (such as copper and galvanized Steel). Plumbing codes in all states require the use of dielectric unions when connecting dissimilar metals. Get it as soon as We Jun 10. It’s a coupling that acts as an electrical barrier between the two metals.

Helps prevent galvanic corrosion when connecting copper and galvanized steel. Dielectric Pipe Unions and Dielectric Gaskets. A dielectric union is a special adapter or fitting used in the piping systems of different metals to isolate the connection of the dissimilar metals.

By the way while on the subject, dielectric NIPPLES are just about worthless because the do not break the circuit at all. Its only intended use is to break continuity. FREE Shipping on orders over $25. Use in water heaters pressure rated to 3psi, water storage tanks, gas piping, air conditioning, water conditioners, oil piping, water pumps and steam lines. CSA low lead content certified.

For example, when connecting a copper pipe to a galvanized iron pipe, a dielectric union is installed between the two to hold the two dissimilar metal pipes together. Fits all Capitol and many other brand unions. Note: Product availability is real-time basis and adjusted continuously. The union is designed to transition between steel and copper piping.

Required where dissimilar metals are used in piping systems, materials for the DUXLC include a zinc-coated steel body, union nut, bolts, and nuts, as well as cast steel flanges, low lead brass tailpiece, nylon insulator, and EPDM gaskets. The IPS connection and nut are both constructed of steel. Help extend installation life, improve system reliability and insure against unexpected maintenance costs. About PEX Universe: PEX Universe (aka PEX-U) is a leading industrial equipment supplier offering high quality heat.

Purpose of dielectric unions is to prevent galvanic corrosion, which is caused by electrolysis. These unions are designed to be installed between pipe made from dissimilar metals to prevent accelerated corrosion and deterioration in the piping system due to galvanic and stray current.
