BrassCraft ProCoat® 3/4 in. Push Connect inlet x 3/4 in. Female Iron Pipe outlet stainless steel connectors. Used to connect the water supply to your water heater, this connector features proprietary push connect technology on the connection to the water piping system and is quick and easy to install. Compatible with copper, CPVC and PEX, no transition fitting is necessary to install. 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.
