Mueller Industries W 07009 Copper End Cap 3/4 in

Product Description

The MUELLER INDUSTRIES W 07009 is a wrot copper pipe end cap designed to terminate 3/4-inch copper tubing using a solder joint connection. Wrot copper construction delivers consistent wall thickness and a smooth interior surface suited for pressure applications in plumbing and hydronic systems. The C-type end connection accepts standard 3/4-inch copper tube, and the 7/8-inch outside diameter fits standard fittings conforming to ASME B16.22. Licensed plumbers and pipefitters install this fitting to permanently cap off a copper branch, stub-out, or service line during new construction, renovation, or system modification.

This end cap is used in residential and light commercial plumbing, heating, and cooling piping systems wherever a copper branch or run must be sealed. It is well suited for domestic water supply, hydronic heating loops, and refrigeration tubing applications requiring a reliable, soldered termination. The fitting meets NSF 61G requirements, making it appropriate for potable water systems. It ships in single-piece package quantity with a minimum order of 5 units.

Installation Notes

Installation is performed by a licensed plumber using standard sweat-soldering tools including a torch, flux, and lead-free solder compliant with local plumbing codes. Shut off and depressurize the supply line and purge residual water from the pipe before applying heat. Clean and flux both the tube end and the fitting cup thoroughly before soldering to ensure a leak-free joint. Follow all applicable IPC and local code requirements for potable water and hydronic applications.
