Ndl Industries W1092 Rolled Stop Copper Coupling

Product Description

The NDL INDUSTRIES W1092 is a rolled stop copper coupling designed for sweat-connect copper tubing systems. The rolled stop inside the fitting seats both pipe ends at a consistent depth, ensuring a uniform solder joint on both sides of the coupling. This fitting uses a C x C (copper by copper) connection type, making it compatible with standard copper tube joined by soldering. It is sized at 3-1/8 inches and is a common choice for licensed plumbers working on domestic water, HVAC refrigerant piping, or hydronic systems where a full-bore copper coupling is required.

This fitting is used in residential and commercial plumbing and mechanical systems wherever copper pipe must be joined or extended. The C x C configuration requires proper flux application and soldering technique per applicable codes. It is installed by licensed plumbers and HVAC technicians working with hard copper tube in new construction, renovation, and repair applications.

Key Features

• Rolled stop positions both pipe ends at a consistent insertion depth for reliable solder joints
• C x C connection type for standard sweat-solder installation
• 3-1/8 inch fitting size suits larger-diameter copper piping runs
• Copper construction provides corrosion resistance and long service life in wet piping systems
• Sold in box quantities of 4

Compatibility

Designed as an OEM-style copper sweat fitting for use with standard 3-1/8 inch copper tube in plumbing and mechanical piping systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical contractor in accordance with the International Plumbing Code or applicable local codes. Shut off and drain the water supply before cutting into any existing piping. Clean and flux all mating surfaces before soldering, and allow the joint to cool completely before restoring system pressure. Do not apply heat near flammable materials without appropriate shielding.
