3/8 inch Copper Adapter Fitting x Male

3/8 inch Copper Male Adapter – Sweat to MIP Connection for Copper-to-Threaded Transitions

The 3/8 inch Copper Male Adapter is a precision-machined fitting designed to transition from copper tubing to a threaded pipe system. It features a sweat (solder) connection on one end and a male NPT thread on the other, allowing for secure integration between dissimilar piping materials.

Constructed from high-grade copper, this adapter is suitable for use in potable water distribution, hydronic heating, and other low- to moderate-pressure piping systems. It meets applicable industry performance and material standards, ensuring compatibility and long-term durability in regulated mechanical installations.

Product Features

• ✅ Copper Body Offers excellent corrosion resistance and thermal conductivity for consistent performance.
• ✅ Male NPT Thread Standardized threading provides compatibility with valves, tees, and iron pipe connections.
• ✅ Sweat Connection Accepts copper tube of matching nominal size for soldered joint construction.
• ✅ Reliable Seal When properly installed with solder and flux, the joint supports leak-free performance under operational pressure and temperature ranges.
• ✅ Code-Compliant Meets lead-free requirements under NSF/ANSI 61 and the Safe Drinking Water Act for use in potable water systems.

Technical Specifications

• Nominal Size: 3/8 inch
• End Connections: Sweat x Male NPT
• Material: Copper (lead-free alloy)
• Applicable Standards: ASME B16.22, ASTM B75, NSF/ANSI 61

Applications

Commonly used in residential and commercial construction, this copper adapter enables transitions in systems such as:

• Potable water distribution lines
• Hydronic baseboard or radiant heating systems
• Valve and fixture branch connections in mechanical rooms

Installation Notes

Use standard soldering procedures for the sweat end, ensuring a clean and dry mating surface. Apply flux before heating and complete the joint with approved lead-free solder. For the threaded end, apply PTFE tape or thread sealant as required by system specifications. Always verify alignment and thread engagement before pressurizing.

The 3/8 inch Copper Male Adapter provides a durable solution for interfacing copper tubing with threaded system components. Its precise dimensions, corrosion resistance, and code compliance make it a dependable choice for professional-grade installations in new construction and retrofits.
