Ndl Industries W1063 Rolled Stop Copper Coupling 1-5/8 in

Product Description

The NDL INDUSTRIES W1063 is a rolled stop copper coupling designed for sweat-connect plumbing and refrigeration piping systems. The rolled stop design positions a machined shoulder inside the fitting body, preventing one pipe end from being pushed through during assembly and ensuring consistent, repeatable solder joint depth on both ends. This coupling uses a C x C (copper-to-copper) connection type and fits 1-5/8 inch nominal tube. It is installed by licensed plumbers and HVAC-R technicians working on refrigerant lines, chilled water systems, or general copper piping runs where a full coupling is required.

This coupling is suited for residential and commercial applications where copper sweat joints are the specified connection method. The 1-5/8 inch size is commonly used in larger-diameter refrigerant suction lines, chilled water branch piping, and commercial HVAC distribution systems. Box quantity of 10 makes it practical for service contractors and mechanical contractors stocking for multi-unit jobs or ongoing maintenance work.

Key Features

• Rolled stop shoulder ensures consistent solder joint depth on both ends
• C x C connection accepts standard copper tubing for sweat soldering
• 1-5/8 inch fitting size suits larger-diameter refrigerant and hydronic piping
• Full copper construction for compatibility with solder and brazing processes
• Sold in a box quantity of 10 for contractor and service-volume use

Compatibility

Designed as an OEM-style sweat coupling for 1-5/8 inch copper tubing in residential and commercial plumbing, HVAC-R refrigerant piping, and chilled water systems where C x C connections are specified.

Installation Notes

Installation is performed by a licensed plumber or HVAC-R technician. Shut off and recover or isolate the system before cutting into any existing line. Clean and deburr tube ends and clean the fitting socket before applying flux and soldering or brazing per applicable code requirements including IFGC and IPC guidelines. Do not use open flame near combustible materials without proper shielding in place.
