Ndl Industries W8002 Copper Union 1/2 Inch

Product Description

The NDL INDUSTRIES W8002 is a 1/2 inch copper union fitting used to join two sections of copper tubing in a way that allows future disconnection without cutting the line. Unions are a standard component in plumbing and HVAC hydronic systems where serviceability matters. The split three-piece design — two threaded end connectors and a center nut — lets a technician break the joint cleanly during equipment swaps or line repairs. This fitting is suited for potable water, hydronic heating, and general plumbing rough-in work. Licensed plumbers and HVAC mechanics are the typical installers.

The W8002 fits 1/2 inch copper tubing and is appropriate for residential and light commercial plumbing systems. Unions of this type are commonly installed at water heaters, boilers, pumps, valves, and any piece of equipment that may require periodic removal. The 50-piece box quantity makes this fitting practical for contractors stocking a service van or staging a multi-fixture rough-in job.

Key Features

• 1/2 inch connection size for standard copper tubing
• Union design allows line separation without cutting pipe
• Copper construction provides corrosion resistance in wet plumbing environments
• Box quantity of 50 supports contractor-volume purchasing

Compatibility

Designed as an OEM-style replacement and standard-stock copper union for 1/2 inch copper tube systems in residential and light commercial plumbing and hydronic HVAC applications.

Installation Notes

Installation of copper unions is performed by licensed plumbers or HVAC technicians in jurisdictions governed by the International Plumbing Code or applicable local codes. Shut off the water supply and relieve system pressure before cutting into an active line. Unions are typically sweat-soldered using a torch and lead-free solder; follow all applicable fire-safety and flux-usage guidelines. Ensure both mating faces are clean and square before tightening the union nut to avoid seat leaks.
