Dielectric Union Galvanized to Pex

When converting galvanized pipes to PEX, it’s important to address the issue of galvanic corrosion that can occur when two dissimilar metals come in contact with each other. The solution to this problem is a dielectric union, which is a special type of fitting that separates the galvanized and PEX pipes to prevent corrosion.

What is a Dielectric Union

A dielectric union is a plumbing fitting that is used to join two pipes made of different metals, such as copper and steel. It consists of two parts: a threaded nut that attaches to the steel or galvanized pipe, and a sleeve that fits over the PEX pipe. The two parts are separated by a rubber gasket or plastic insulator that prevents direct contact between the two metals.

How Does a Dielectric Union Work

Galvanic corrosion occurs when two dissimilar metals are in contact with each other in the presence of an electrolyte, such as water. The metal that is more reactive (i.e., less noble) corrodes faster than the other metal. In the case of galvanized pipes and PEX pipes, the galvanized steel is more reactive than the brass or copper fittings used in the PEX system.

A dielectric union prevents galvanic corrosion by creating an insulating barrier between the two metals. By separating the galvanized steel from the PEX pipe with a non-conductive material, it prevents the flow of electrons that causes corrosion. This ensures that the PEX system remains corrosion-free and lasts for many years.

Why is a Dielectric Union Important

Without a dielectric union, galvanic corrosion can cause leaks, reduced water pressure, and other plumbing problems. It can also shorten the lifespan of the PEX system, leading to costly repairs or replacements. By using a dielectric union, you can prevent these issues and ensure that your PEX system functions properly for many years.

Converting galvanized pipes to PEX is a smart choice for many homeowners, but it’s important to address the issue of galvanic corrosion that can occur. A dielectric union is an essential component of any PEX system that is connected to galvanized pipes. By providing an insulating barrier between the two metals, it prevents galvanic corrosion and ensures that your system functions properly for many years to come.
