Mueller Industries W 07007 Wrot Copper End Cap 1/2 in

Product Description

The MUELLER INDUSTRIES W 07007 is a wrot copper pipe end cap designed to terminate 1/2 inch copper tubing using a standard solder joint (type C) connection. Wrot copper construction provides superior pressure handling and corrosion resistance compared to cast fittings, making this cap suitable for potable water, HVAC hydronic, and refrigeration piping systems. The fitting meets multiple ASME dimensional and pressure standards and carries NSF 61G certification for use in drinking water applications. Licensed plumbers and HVAC technicians install this fitting as part of system commissioning, pressure testing, or permanent line termination.

This end cap is used in residential and light commercial plumbing and hydronic systems wherever a copper run requires permanent closure. Typical applications include capping unused branch outlets, sealing test points after pressure verification, and terminating supply or return lines during phased construction. The 1/2 inch size is one of the most common in residential domestic water and low-pressure hydronic distribution piping.

Key Features

• Wrot copper construction for higher strength and smoother interior surface than cast alternatives
• Type C solder joint end connection compatible with standard copper tubing and 95/5 or lead-free silver solder
• NSF 61G certified for potable water contact
• Meets ASME B16.22 and ASME B16.18 dimensional standards for consistent fitment
• Outside diameter of 5/8 inch ensures correct overlap for reliable sweat connection

Compatibility

Designed as an OEM-style solder-joint end cap for 1/2 inch copper tubing in residential and commercial plumbing, HVAC hydronic, and related piping systems where ASME B16.22 or B16.18 fittings are specified.

Installation Notes

Installation is performed by a licensed plumber or qualified HVAC technician. Shut off and depressurize the system and purge all moisture from the pipe before soldering. Clean the tube end and fitting socket with emery cloth and apply appropriate lead-free flux before making the sweat connection. Work must conform to applicable local plumbing codes and ASME standards referenced for this fitting.
