3/4 inch Copper Adapter Fitting x Male

3/4 inch Copper Male Adapter – Sweat x MIP for Copper-to-Threaded Transitions

The 3/4 inch Copper Male Adapter is a transition fitting used to connect copper tubing to a threaded pipe or valve. With a solder (cup) end and a male NPT thread, this fitting enables reliable joining of copper water lines to fittings or fixtures with female threads, eliminating the need for additional unions or couplings.

Manufactured from lead-free wrought copper, this adapter conforms to applicable plumbing codes and standards for potable water applications. The fitting is engineered with precision-machined threads and consistent socket depth to ensure proper joint integrity during soldering.

Key Attributes for Field Use

• ✅ Lead-Free Copper – Fabricated from copper alloy that complies with NSF/ANSI 61 and 372 standards for use in potable water systems.
• ✅ Connection Type: Copper Socket x Male NPT – Accepts copper tubing on one end and connects to threaded pipe or valves on the other.
• ✅ Code-Compliant Construction – Designed in accordance with ASME B16.22 and ASTM B75 for pressure-rated plumbing systems.
• ✅ Thread Integrity – NPT threads meet ANSI B1.20.1, providing a consistent and leak-resistant threaded joint when installed with approved sealant.
• ✅ Temperature & Pressure Rated – Rated for 200 PSI at 180°F when properly soldered and installed.
