About Dielectric Unions

Dielectric Unions are an important conduit fitting used to connect different types of pipes together. They provide a secure and reliable connection between two pieces of piping, preventing corrosion or other damage that could be caused by dissimilar materials coming into contact with one another.

Types of Dielectric Unions

Dielectric Unions come in a variety of sizes and shapes to fit the needs of any job. Depending on the application, they may include dielectric nipples or unions, dielectric pipe couplings, stainless steel to brass dielectric unions, and sharkbite dielectric unions. Each type is designed for specific applications, so it’s important to choose the right one for your project.

How Dielectric Unions are Made

Dielectric Unions are made from a variety of materials such as brass, copper, steel, and plastic. The union consists of two end fittings that are connected by a nut and washer assembly which creates a tight seal between the two pipes when tightened. This prevents any current from passing through the joint.

Industries that use Dielectric Unions

Dielectric Unions are commonly used in plumbing, gas piping, electrical conduit installation and many other industries where connections need to be made between two different types of material. Professionals must know when to use them in order to ensure proper installation and prevent leaks or damage.
