Mueller Industries a 11207NL 2 Inch Copper Union C X C

Product Description

The MUELLER INDUSTRIES A 11207NL is a wrot copper pipe union designed for 2-inch C x C (copper-to-copper) solder joint connections in pressure piping systems. Manufactured from wrot copper, this union provides a reliable, high-integrity joint suitable for potable water, hydronic heating, and general plumbing applications. The fitting is fully lead free, meeting current Safe Drinking Water Act requirements. With an outside diameter of 2.125 inches and a weight of approximately 1.5 pounds, it is sized for standard 2-inch copper tubing. Licensed plumbers and pipefitters are the typical installers for this type of fitting.

This union is suited for residential and commercial plumbing systems where a serviceable, demountable copper connection is required. It is commonly installed in mechanical rooms, boiler piping, domestic water distribution, and HVAC hydronic loops where future disassembly without cutting pipe is necessary. The C x C solder joint end connections accept standard 2-inch copper tubing and are joined using conventional sweat-soldering technique.

Key Features

• Lead free construction compliant with Safe Drinking Water Act requirements
• Wrot copper material provides superior pressure rating and joint integrity versus cast fittings
• C x C solder joint ends for standard sweat connection to 2-inch copper tubing
• Outside diameter of 2.125 inches fits standard 2-inch copper pipe schedule
• Meets ASME B16.22 and multiple additional ASME dimensional and performance standards
• Demountable union design allows piping system service without cutting

Compatibility

Designed as an OEM-style replacement and new-installation fitting compatible with standard 2-inch wrot copper solder joint piping systems conforming to ASME B16.22.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and ASME standards. Shut off and depressurize the water supply and fully drain the line before soldering; residual water in the pipe will prevent the joint from reaching proper solder temperature. Use appropriate flux and lead free solder rated for potable water service. Allow the joint to cool completely before restoring system pressure and inspecting for leaks.
