Ndl Industries w1047 Copper Coupling 1-1/8 in C X C

Product Description

The NDL INDUSTRIES w1047 is a rolled stop copper coupling designed for sweat-connect copper tubing installations in plumbing and HVAC systems. The rolled stop feature positions tubing ends at a consistent depth, ensuring repeatable, leak-free solder joints every time. With a 1-1/8-inch diameter and a copper-by-copper (C x C) end configuration, this fitting handles standard type L and type K tubing in both residential and light commercial applications. Licensed plumbers and HVAC technicians rely on this type of coupling for straight-run connections and repair work where tubing alignment and joint integrity are critical.

This coupling is suited for use in domestic water supply lines, hydronic heating piping, refrigeration suction lines, and general copper tubing distribution systems. The 1-1/8-inch size is commonly found in larger residential water mains, commercial chilled-water circuits, and refrigerant suction-line segments where full-bore flow is required. The C x C connection style requires standard silver-bearing or lead-free solder and copper-compatible flux per local plumbing code requirements.

Key Features

• Rolled internal stop sets tubing seating depth automatically for consistent joint depth on both ends
• C x C (copper sweat) end connections compatible with standard copper tubing prep tools
• 1-1/8-inch nominal size supports full-bore flow in larger distribution and refrigeration circuits
• Copper construction provides corrosion resistance and long service life in wet environments
• Lead-free solder compatible and suitable for potable water systems where code-compliant solder and flux are used

Compatibility

Designed as an OEM-style sweat fitting replacement for 1-1/8-inch copper tubing systems using standard C x C copper coupling configurations in plumbing and HVAC piping.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician familiar with copper sweat-soldering techniques. Shut off and drain the affected water or refrigerant circuit before cutting into any existing line. Clean all tubing ends and fitting sockets with emery cloth and apply an approved flux before soldering, following ASTM B32 solder standards and applicable local plumbing codes such as the IPC or UPC. Do not use open-flame torches near combustible materials without proper heat shielding in place.
