Value Collection 168-094NL Dielectric Union 3/4 X 1/2

Product Description

The VALUE COLLECTION 168-094NL is a dielectric union fitting used to join dissimilar metals in plumbing systems while preventing galvanic corrosion. The fitting transitions between a 3/4-inch connection and a 1/2-inch connection and is available in FNPT, MNPT, and sweat end configurations. Dielectric unions are a code-required component in many jurisdictions wherever copper and steel pipe meet, such as at water heater connections. The fitting measures 2.75 inches in height and 1.75 inches in width and length, and weighs 0.4 pounds. It is installed by licensed plumbers and qualified pipefitters in both residential and light commercial applications.

This dielectric union is suited for potable water supply lines, water heater inlet and outlet connections, and other plumbing assemblies where copper pipe meets steel or galvanized pipe. The 3/4-inch sweat end accommodates standard copper tubing, while the threaded ends accept standard NPT fittings. The compact package size makes it practical for single-point repairs or new installations. It ships as a single-unit package, making it easy to stock individually for service calls.

Compatibility

Designed as an OEM-style replacement or new-installation dielectric union for residential and light commercial plumbing systems where copper and ferrous pipe materials meet at threaded or sweat connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and depressurize the line before beginning work. Use appropriate thread sealant or PTFE tape on NPT threads and proper flux and solder technique on sweat connections. Do not over-tighten threaded ends, as this can crack the dielectric sleeve and defeat the corrosion-isolation function of the fitting.
