Ndl Industries W1906 No Stop Copper Coupling 1-1/8 in Cxc

Product Description

The NDL INDUSTRIES W1906 is a no-stop copper coupling designed for sweat-connect plumbing applications where a standard internal stop would interfere with the joint. Sized at 1-1/8 inches with a C x C (copper-to-copper) connection type, this fitting allows a pipe to slide fully through the fitting without obstruction. That makes it particularly useful when repairing existing lines or making in-wall connections where pulling pipe back is not an option. Licensed plumbers and pipe fitters are the typical installers. The W1906 is fabricated from copper, offering reliable corrosion resistance and long service life in both hot and cold water systems.

This no-stop coupling is suited for residential and light commercial plumbing repair and rough-in work. It is commonly used when splicing into existing copper runs where a stop-type coupling cannot be seated properly. The C x C connection type requires standard solder and flux for a sweat-joined installation. Applications include domestic water supply lines, hydronic heating piping, and similar copper-based systems operating within standard pressure and temperature ranges for copper fittings.

Key Features

• No internal stop allows full pipe insertion for repair and splice applications
• 1-1/8 inch C x C connection size for copper-to-copper sweat joints
• Copper construction provides corrosion resistance and long service life
• Compact coupling profile suited for tight spaces and in-wall repairs

Compatibility

Designed as an OEM-style replacement and repair fitting for 1-1/8 inch copper pipe systems using sweat-type C x C connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and fully drain the line before cutting into existing pipe. Clean and flux all mating surfaces thoroughly before applying heat to ensure a leak-free sweat joint. Allow the fitting to cool completely before restoring system pressure and inspecting for leaks.
