3/4 inch Copper Adapter Fitting x Male

3/4” Copper Male Adapter – Solder Cup x MIP for Copper-to-Threaded Transitions

The 3/4” copper male adapter is designed for transitioning from copper tubing to threaded connections in potable water and mechanical piping systems. One end features a solder cup for joining to copper tube, while the opposite end is machined with male NPT threads for connection to valves, fittings, or threaded components in hot and cold water systems.

Manufactured from lead-free wrought copper (ASTM B75 Alloy C12200), this fitting meets ASME B16.22 dimensional standards and is certified for potable water applications under NSF/ANSI 61 and 372. Suitable for both residential and commercial systems, this adapter is used extensively in water distribution, HVAC systems, and hydronic piping.

Technical Specifications

• Nominal Size: 3/4 inch
• Connection Type: Solder Cup x Male NPT
• Material: Lead-free wrought copper (C12200)
• Pressure Rating: Up to 200 PSI (non-shock for water applications)
• Certifications: NSF/ANSI 61 and 372, ASME B16.22 compliant

Key Performance Features

• ✅ Threaded Transition – Connects copper tube to female-threaded valves, meters, or pipe
• ✅ Lead-Free Composition – Complies with U.S. Safe Drinking Water Act requirements
• ✅ Pressure and Temperature Resistance – Suitable for domestic water and hydronic systems up to 400°F (based on solder alloy)
• ✅ Machined Thread Ends – Manufactured to NPT standards for leak-resistant threaded connections

Installation Notes

Clean and flux copper tube and fitting prior to soldering with an approved lead-free solder. Use PTFE tape or pipe thread sealant on the male thread when joining to female-threaded components. Avoid overtightening during installation to prevent damage to threads. Not intended for underground use unless protected per local code.

Typical Applications

Used in potable water supply lines, heating loops, and process piping systems where copper-to-threaded transitions are required. Suitable for installation in mechanical rooms, wall cavities, and equipment tie-ins in both new construction and retrofit applications.

Material and Code Note

This adapter conforms to federal and state lead-free mandates and is acceptable for use in all jurisdictions where compliance with NSF/ANSI 372 is required. Wrought copper fittings offer long service life, ease of soldering, and dimensional stability under thermal cycling.

The 3/4” copper male adapter provides a reliable, code-approved solution for connecting copper tube to threaded piping or equipment across a wide range of water and mechanical systems.
