Homewerks Worldwide Llc 520-12-1 Dielectric Union Washer

Product Description

The HOMEWERKS WORLDWIDE LLC 520-12-1 is a 1/2 inch copper dielectric union washer designed to isolate dissimilar metals in plumbing connections. Dielectric unions prevent galvanic corrosion at the joint between copper and steel piping by introducing a non-conductive barrier between the two metals. This washer is a key component in that assembly. Plumbers and pipefitters install these during new construction and service work wherever copper supply lines connect to steel or galvanized iron fittings. Each pack contains 10 washers sold as a single unit of measure.

This washer is used in residential and light commercial plumbing systems at points where copper transitions to ferrous pipe. Common install scenarios include water heater connections, boiler supply and return lines, and any cold or hot water distribution system requiring a copper-to-steel transition. The 1/2 inch sizing fits standard half-inch dielectric union assemblies.
