1 inch Copper Adapter Fitting x Male

1 inch Copper Adapter – Lead-Free Sweat x Male Pipe Fitting for Potable Systems

This 1 inch copper adapter fitting is designed for joining a copper tube to a threaded pipe system. One end features a socket (sweat) connection for copper tubing, while the opposite end provides a male NPT thread for transitioning to other materials or system components.

Manufactured from lead-free wrought copper alloy, this adapter meets current federal, state, and local codes for use in potable water systems. It is commonly used in both hot and cold water distribution lines, HVAC systems, and hydronic heating installations.

Key Product Features

• ✅ Connection Type: Copper sweat x Male NPT
• ✅ Material: Lead-free copper alloy (compliant with NSF 61-G and NSF 372)
• ✅ Pressure Rating: Suitable for use in pressure and non-pressure applications up to 200 psi at 150°F (based on system design)
• ✅ Compatibility: Designed for ASTM B88 Type L and Type M copper tubing
• ✅ Standards: ASME B16.22, ANSI/NSF 61, ANSI/NSF 372, and certified to UPC/IAPMO and CSA B125.3

Installation Notes

This fitting is intended for soldered connections on the copper side. Prior to installation, clean the tubing and fitting socket, apply appropriate flux, and solder using lead-free solder alloys. For the threaded end, use an approved thread sealant or PTFE tape. Always verify compatibility with piping system pressure and temperature ratings, and follow applicable code requirements.

Applications

Used in water supply lines, hydronic heating circuits, and branch terminations where a transition from copper tubing to threaded components is needed. Also suitable for installations in commercial buildings, mechanical rooms, and residential utility applications.

Regulatory Note

As of January 2014, the Safe Drinking Water Act requires all fittings used in potable water systems to be lead-free (<0.25% lead content). This adapter complies with those requirements.

This 1 inch copper adapter provides a code-compliant and mechanically secure solution for transitions between soldered copper pipe and threaded fittings. Its performance under pressure, temperature resistance, and dimensional precision make it a reliable choice for professional-grade systems. ????️
