Definition - What does Dielectric Fitting mean?

A dielectric fitting is a type of industrial material that isolates monitoring instruments against the effects of electrical current. One of its main purposes is to connect two types of pipe, such as iron and copper. It holds the pipes together, averting leakage and other types of damage.

Dielectric fittings disrupt the flow of cathodic current while allowing the fluid to flow. It is often utilized in water supply lines as well as other connections that necessitate an adapter between two dissimilar pipes.

Corrosionpedia explains Dielectric Fitting

A dielectric fitting is specifically designed to join two types of metal pipes together without the need for soldering. It is highly important as when iron and copper pipes are combined, galvanization may take place resulting in corrosion, and eventually, total failure of the pipe system.

A dielectric fitting offers a barrier between the pipes, breaking all galvanized current and preventing corrosion in the pipes. This helps in preserving the pipes and stopping the unintentional production of electricity, which could lead to damage brought by corrosive actions.

Galvanic corrosion takes place when two dissimilar metals are present along with acidic solutions. This type of environment creates a battery that produces electrical current flow between the metals. To keep this from happening, a dielectric fitting is used, as it also serves as an insulator between two metals, putting a stop to electrolysis.
