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.
