1-1/4 inch Copper Coupling with Stop Copper x Copper

1-1/4 inch Copper Coupling – Wrot Copper, C x C, Lead-Free

The 1-1/4 inch copper coupling is a solder-joint (C x C) fitting designed for connecting two pieces of copper tubing in straight runs. Manufactured from lead-free wrot copper, this fitting meets ASTM and NSF standards for use in potable water systems and is suitable for both commercial and residential applications.

Engineered to ensure consistent joint quality and system integrity, this coupling is used in pressurized and non-pressurized piping systems, including water supply, hydronic heating, and chilled water distribution networks.

Product Features

• ✅ Material: Wrot copper alloy (typically UNS C12200), lead-free for compliance with federal and state plumbing regulations.
• ✅ Connection Type: Copper x Copper (C x C), designed for solder (sweat) connections using standard joining techniques.
• ✅ Nominal Size: 1-1/4 inch – compatible with Type K, L, or M copper tubing.
• ✅ Low Flow Resistance: Full bore design supports consistent water flow without restriction.
• ✅ Pressure-Rated: Suitable for systems operating under standard working pressures and temperatures, when properly installed.

Installation Considerations

Preparation requires proper cleaning and flux application on both tubing and fitting ends. The joint is completed by soldering per standard procedures. Ensure correct heating and cooling cycles to avoid joint fatigue or incomplete bonding. Compliance with applicable plumbing codes (e.g., IPC, UPC) is required.

Typical Applications

This coupling is used in a wide range of plumbing systems including potable water distribution, hydronic heating loops, and chilled water piping. It is frequently installed in both new construction and retrofit work, particularly where straight-line continuity of copper pipe is needed.

Material and Compliance Note

Lead-free copper fittings are required under the Safe Drinking Water Act (SDWA) for use in systems delivering potable water. This product meets ANSI/NSF 61 and NSF 372 standards and is listed by third-party certification agencies for compliance.
