Dielectric Couplers
Extending the life of piping systems

We manufacture brass and zinc plated Dielectric couplers with rubber washers and plastic sleeves to ensure this electrical barrier.
We use DZR brass and lead free brass depending on specific applications.




Electrolysis happens 
when pipe systems of different metal alloys are connected together, glavanic and stray currents cause electrolisys in the piping systems which vastly accellerate corrosion and deterioration of the piping systems. The result is leaking pipes, insurance claims, expensive refurbishment costs and wasted time.

The installation of Dielectric Fittings creates an electrical barrier between the different pipe systems. This stops galvanic and stray currents which cause electrolysis of the pipe systems. Therefore it is common sense when connecting your commercial or residential reticulation systems to use dielectric fittings, for peace of mind.
