stainless steel to copper pipe connection

Joining copper and stainless steel pipes is a common requirement when it comes to plumbing. Luckily, various options are available for connecting these two materials; the optimal technique, however, is by using a dielectric union. This method is well-known in the field and delivers excellent results in most cases.

To protect against corrosion, a dielectric union is constructed from two half-couplings, one made of stainless steel and the other of copper. A sleeve of electrically resistant material, like PTFE, is sandwiched between the two and bound securely in place with a combination of a nut and ferrule. This device bridges the connection between two distinct kinds of piping while forming a barrier that obviates electric currents between them.

When uniting stainless steel and copper pipe, dielectric unions are the option of choice. Nothing compares to their effortless installation and secure, lasting connection that will not succumb to corrosion. Unlike soldering or mechanical coupling units that require more labor-intensive setup and are less dependable, the advantages of utilizing dielectric unions are undeniable.
