Ndl Industries W1072 Rolled Stop Copper Coupling 2-1/8 in

Product Description

The NDL INDUSTRIES W1072 is a rolled stop copper coupling designed for joining copper tubing in sweat-soldered plumbing and HVAC refrigeration piping systems. The rolled stop inside the fitting seats tubing ends at a consistent depth, ensuring proper joint alignment before soldering. Sized at 2-1/8 inches with a C X C (copper-by-copper) connection type, this coupling is a standard component in residential and commercial mechanical systems. Licensed plumbers and HVAC technicians are the primary installers. It ships in a box quantity of 6, making it practical for service fleets and supply carts that handle recurring pipe-joining work.

This coupling is suited for use in copper tube runs where a full-bore, pressure-rated sweat connection is required. The 2-1/8 inch nominal size places it in the larger-diameter range common to commercial refrigeration suction lines, hydronic mains, and larger domestic water distribution headers. It is appropriate for any application where copper is the specified pipe material and a reliable stop-depth fitting is preferred for consistent solder joint quality.

Key Features

• Rolled internal stop seats tubing at a fixed depth for repeatable, properly aligned sweat joints
• C X C connection type accepts standard copper tubing on both ends
• 2-1/8 inch size fits larger-diameter copper tube runs in commercial and residential systems
• Full copper construction provides corrosion resistance and solderability consistent with industry standards
• Sold in a box quantity of 6 for multi-joint service calls and installation projects

Compatibility

Designed as an OEM-style sweat coupling for 2-1/8 inch copper tubing systems using C X C (copper-by-copper) connections in plumbing, HVAC, and refrigeration piping applications.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians following applicable local plumbing codes and IFGC or IPC guidelines where relevant. Shut off the water or refrigerant supply and depressurize the line before cutting and fitting. Clean and flux both tube ends and the fitting socket thoroughly before applying heat with a torch; overfitting without proper flux is a common cause of void joints. Allow the completed joint to cool fully before restoring system pressure and inspecting for leaks.
