Ndl Industries W8003 Copper Union 5/8 Inch

Product Description

The NDL INDUSTRIES W8003 is a 5/8-inch copper union fitting designed for joining two sections of copper tubing in a way that allows future disconnection without cutting the line. Copper unions are a standard component in plumbing and HVAC refrigerant or hydronic piping systems where serviceability matters. The fitting uses a three-piece design — two end connections and a center nut — that lets a technician break the joint cleanly during equipment swaps or repairs. Licensed plumbers and HVAC mechanics are the primary installers of this type of fitting.

This union is suited for residential and light commercial applications where 5/8-inch copper tubing is run for water supply, hydronic heating loops, or other fluid-handling systems. The 5/8-inch connection size corresponds to common tubing used in a range of piping configurations. It ships in a box quantity of 25 units, making it practical for contractors stocking a van or completing multi-fixture jobs.

Key Features

• 5/8-inch connection size for standard copper tubing applications
• Three-piece union design allows line disconnection without cutting pipe
• Copper construction provides corrosion resistance in fluid-handling systems
• Box quantity of 25 units supports multi-fixture or stocking orders

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 5/8-inch copper tubing systems in residential and light commercial plumbing or HVAC piping applications.

Installation Notes

Installation is performed by a licensed plumber or HVAC technician. Shut off and depressurize the supply line before cutting into any existing piping. The joint ends are typically sweated using lead-free solder in accordance with applicable plumbing codes such as the IPC. Ensure all mating surfaces are clean and deburred before assembly to achieve a leak-free connection.
