Ndl Industries W1075 Copper Reducing Coupling 2-1/8x1-1/8 Cxc

Product Description

The NDL INDUSTRIES W1075 is a copper reducing coupling designed to connect two copper tube runs of different diameters in a single in-line joint. It transitions from a 2-1/8 inch socket to a 1-1/8 inch socket using a standard sweat (C x C) connection on both ends. The fitting is intended for use in refrigeration, HVAC, and plumbing piping systems where a reduction in line size is required. Licensed plumbers and HVAC technicians are the primary installers. The C x C connection style means both ends accept copper tubing that is cleaned, fluxed, and soldered to a standard pressure-tight joint.

This reducing coupling is suited for residential and light commercial applications where copper piping must step down from a 2-1/8 inch main line to a 1-1/8 inch branch or equipment connection. Typical scenarios include suction line transitions in refrigeration systems, main-to-branch connections in hydronic piping, and rework or repair situations where pipe sizing changes at a tee or equipment stub-out. Box quantity is 15 units, making it practical for contractors stocking common reducing fittings on service vehicles or in shop inventory.

Key Features

• Reduces from 2-1/8 inches to 1-1/8 inches in a single in-line fitting
• C x C connection type — both ends accept standard sweat solder joints
• Copper construction for compatibility with standard copper tube systems
• Sold in a box quantity of 15 units
• Straightforward in-line installation with no offset or angle

Compatibility

Designed as an OEM-style copper reducing coupling for use with standard copper tubing in HVAC, refrigeration, and plumbing piping systems requiring a C x C sweat connection at 2-1/8 inch by 1-1/8 inch sizing.

Installation Notes

Installation is performed by a licensed plumber or HVAC technician following applicable local mechanical and plumbing codes. Before soldering, shut off and depressurize the system, then clean and flux both the tube ends and fitting sockets thoroughly. Use the appropriate torch and lead-free solder per code requirements. Allow the joint to cool completely before restoring system pressure and checking for leaks.
