1-1/2 inch Copper Coupling less Stop Copper x Copper

1-1/2” Copper Coupling – Seamless Fit for High-Performance Plumbing

The 1-1/2” copper coupling is engineered for joining copper tube sections in potable water, hydronic heating, and DWV systems. Manufactured from lead-free, wrought copper (typically ASTM B75 Alloy C12200), this fitting provides a reliable and permanent connection when properly soldered or brazed. Its compact design ensures ease of installation while maintaining flow integrity throughout the system.

Key Performance Features

• ✅ Uniform Wall Thickness: Maintains consistent pressure ratings across installations.
• ✅ Lead-Free Compliance: Suitable for use in all potable water systems per NSF/ANSI 61 and NSF/ANSI 372.
• ✅ Optimized for Sweat Connections: Ends are sized to accept nominal copper tube for secure soldered joints.
• ✅ High Thermal Resistance: Withstands high-temperature applications when used with proper joining methods.
• ✅ Corrosion Resistance: Copper alloy offers natural protection against scaling and rust.

Typical Applications

This coupling is commonly used in residential, commercial, and institutional piping networks. It is ideal for new construction, service repair work, and system retrofits where consistent, leak-free connections are critical.

Installation Notes

Installation should follow standard copper tube joining practices per ASTM B828 and local code requirements. Surfaces must be clean and fluxed prior to soldering. For optimal results, ensure proper tube insertion depth and heating profile during assembly. Not intended for use with press-fit systems or threaded joints.
