Ndl Industries w1055 Copper Coupling 1-3/8 in C X C

Product Description

The NDL INDUSTRIES w1055 is a rolled stop copper coupling designed for sweat-connect copper pipe installations in plumbing and HVAC systems. The rolled stop feature provides a built-in pipe stop that seats each pipe section at a consistent depth, ensuring proper joint alignment and solder penetration. This coupling uses a copper-to-copper (C x C) connection type and is sized for 1-3/8 inch pipe. It is typically installed by licensed plumbers and HVAC technicians working on refrigerant line sets, water distribution systems, or hydronic piping.

This coupling is suited for residential and light commercial applications where a reliable, leak-free sweat joint is required. The C x C end configuration accepts standard copper tubing on both ends, making it a straightforward choice for straight-run repairs, extensions, and new installations in wet or dry piping systems.

Key Features

• Rolled stop design seats pipe at consistent depth for repeatable solder joints
• C x C (copper-to-copper) sweat connection on both ends
• 1-3/8 inch pipe size for larger-diameter plumbing and refrigerant applications
• Copper construction provides corrosion resistance and long service life
• Compatible with standard sweat soldering and brazing techniques

Compatibility

Designed as an OEM-style replacement and general-use fitting for 1-3/8 inch copper pipe in sweat-connect plumbing, HVAC, and hydronic piping systems.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician familiar with sweat soldering or brazing procedures. Shut off and depressurize the system and drain standing water from the pipe before cutting and fitting. Use appropriate flux and solder or brazing alloy rated for the application, and follow all applicable local plumbing codes and IFGC or IPC requirements. Allow the joint to cool fully before restoring system pressure.
