Made from Buna-N rubber, this washer provides a reliable seal within the union body, preventing galvanic corrosion between dissimilar metals in plumbing systems. It is a direct drop-in replacement for worn or damaged washers in standard dielectric union assemblies. Licensed plumbers and pipefitters install this component during routine maintenance or repair of domestic water supply lines, particularly where copper and galvanized steel piping are joined.\u003c\/p\u003e\n\u003cp\u003eThis washer fits 3\/4 inch dielectric unions and is suitable for residential and light commercial plumbing applications. It is compatible with Mueller, BK, and other standard dielectric union brands that use the same washer geometry. The Buna-N rubber construction makes it appropriate for potable water service where a durable, compressible seal is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N rubber construction for durable compression sealing\u003c\/li\u003e\n  \u003cli\u003eSized for 3\/4 inch dielectric union assemblies\u003c\/li\u003e\n  \u003cli\u003eDirect replacement for worn or degraded union washers\u003c\/li\u003e\n  \u003cli\u003eCompatible with Mueller, BK, and comparable union brands\u003c\/li\u003e\n  \u003cli\u003eSold individually — minimum order quantity of 5 units\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with Mueller, BK, and other brand dielectric unions using a standard 3\/4 inch rubber washer.
