2-1/2 inch Copper Adapter Fitting x Male

2-1/2 inch Copper Adapter – Sweat x Male Pipe Connection for Potable and Mechanical Systems

The 2-1/2 inch copper adapter is designed to transition copper tubing to threaded piping components. One end features a solder (sweat) socket connection suitable for copper tube, while the other terminates in a male NPT thread for joining to valves, fittings, or equipment with female-threaded ports.

Manufactured from lead-free copper alloy, this fitting is compliant with federal Safe Drinking Water Act requirements and is suitable for use in potable water distribution, hydronic heating loops, and mechanical piping systems. It is compatible with ASTM B88 copper tube and meets ASME B16.22 dimensional standards.

Key Product Features

• ✅ Connection Type: Solder x Male NPT
• ✅ Material: Lead-free wrought copper (compliant with NSF/ANSI 61 & 372)
• ✅ Standards: ASME B16.22, third-party certified to UPC, NSF, and CSA requirements
• ✅ Applications: Hot/cold water systems, HVAC, hydronic distribution, and non-combustible systems
• ✅ Operating Range: Up to 200 psi at 150°F (based on solder joint method and copper type)

Installation Guidelines

Installation requires copper pipe preparation and lead-free soldering. Clean the tube and socket ends, apply approved flux, and use heat and solder appropriate for potable water systems. The male threaded end should be wrapped with PTFE tape or applied with thread sealant. Always ensure compatibility with system pressure and temperature specifications.

Common Use Cases

This fitting is commonly used in large-diameter copper piping networks in commercial plumbing, municipal service entry piping, and industrial mechanical systems. Also applied in pump connections, expansion tank loops, and vertical risers where threaded transitions are required.

Compliance Note

All copper fittings intended for drinking water must meet lead-free standards under federal and state law. This product satisfies those requirements with a maximum weighted lead content of 0.25%.

The 2-1/2 inch copper sweat x male adapter offers a reliable, code-compliant solution for professional-grade plumbing and mechanical installations. Designed for durability and performance in demanding conditions. ????️
