Mueller Industries W 07006 Wrot Copper End Cap 3/8 in

Product Description

The MUELLER INDUSTRIES W 07006 is a wrot copper pipe end cap designed to terminate 3/8 inch copper tubing lines using a solder joint C connection. Wrot copper construction provides superior strength and pressure resistance compared to cast fittings, making this cap a reliable choice for permanent pipe terminations in plumbing, HVAC, and refrigeration piping systems. The fitting has an outside diameter of 1/2 inch and weighs approximately 0.01 pounds. It meets multiple ASME and NSF standards, confirming suitability for potable water and mechanical system applications. Licensed plumbers and HVAC technicians are the primary installers of this fitting type.

This end cap is used in residential and light commercial plumbing and HVAC piping where a copper branch or run must be permanently closed off. Common applications include capping unused ports on distribution manifolds, terminating stub-outs during rough-in, and closing off decommissioned supply lines. The solder joint C end connection is the standard sweat-style connection used throughout copper tubing systems in both water supply and refrigerant piping contexts.

Key Features

• Wrot copper construction for higher strength and pressure rating versus cast copper
• 3/8 inch fitting size with 1/2 inch outside diameter
• Solder joint C connection for standard sweat installation
• Meets ASME B16.22, ASME B16.18, ASME B16.15, and NSF 61G standards
• Lightweight at approximately 0.01 pounds for easy handling in tight spaces

Compatibility

Designed as an OEM-style replacement and standard-use end cap compatible with 3/8 inch copper tubing systems using solder joint C connections in plumbing and HVAC applications.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians using standard sweat-soldering tools including a torch, flux, and lead-free solder in compliance with local plumbing codes and ASME B16.22 requirements. Shut off and depressurize the water or refrigerant line and ensure the pipe end is clean, dry, and deburred before soldering. Do not apply heat to a pressurized or wet line. Follow all applicable local and national plumbing codes, including IPC and IFGC guidelines where relevant.
