2 inch Copper Adapter Fitting x Male

2 inch Copper Male Adapter – Lead-Free Wrot Copper Fitting for Solder-to-Thread Transitions

The 2 inch copper male adapter is a solder-joint x male-threaded fitting used to transition from copper tube to threaded pipe or valves in pressurized plumbing systems. Manufactured from lead-free wrought copper, this fitting complies with current potable water codes and supports high-integrity connections in domestic, commercial, and hydronic systems.

It features a solder cup on one end for sweat connections to copper tubing, and a male NPT thread on the other for threaded fittings, valves, or other metallic components. The adapter is designed to meet dimensional and performance requirements under ASME and NSF standards.

Technical Specifications

• Material: Lead-free wrought copper (ASTM B75 / UNS C12200)
• Nominal Size: 2 inches
• Connection Type: Solder Cup x Male NPT Thread
• Standards: ASME B16.22, NSF/ANSI 61 & 372
• Application: Potable water, chilled water, and hydronic systems

Approved Use Cases

• Domestic water distribution (hot and cold lines)
• Transitioning copper tubing to threaded valves or brass manifolds
• Boiler connections and equipment tie-ins in hydronic systems
• Service or repair work where disassembly may be required

Installation Notes

Install the solder end using lead-free solder or brazing alloy with appropriate flux. Ensure proper pipe cleaning, deburring, and preheating to achieve a full-depth joint. The male threaded end should be sealed with PTFE tape or approved pipe joint compound before tightening into a female-threaded fitting. Avoid over-torquing to prevent thread distortion.

Compliance and Material Considerations

This fitting meets the lead content requirements of the U.S. Safe Drinking Water Act (SDWA) and is third-party certified for use in potable water systems. Wrot copper offers excellent corrosion resistance and thermal performance in a variety of pressurized systems.

Summary

The 2 inch copper male adapter is a code-compliant solution for transitioning from soldered copper tube to threaded connections. Its durable lead-free construction and dimensional accuracy make it a reliable choice for new construction, system upgrades, and mechanical retrofits where copper tubing is used in conjunction with threaded components.
