BrassCraft® ProCoat® 3/4 in Female Iron Pipe inlet x 3/4 in Female Iron Pipe outlet stainless steel connector. Used to connect the water supply to your water heater, this connector delivers outstanding flexibility with advanced corrosion resistance, both inside and outside. BrassCraft®'s patented integrated dielectric sleeve isolates dissimilar metals within the waterway, where galvanic and electrolytic corrosion have their greatest potential. This separation provides complete protection against galvanic corrosion that can deteriorate the connector and cause leaks. In addition, the integrated dielectric sleeve eliminates the need to install an additional dielectric union, reducing time and installation costs.
