Ndl Industries W1083 Copper Reducing Coupling 2-5/8x2-1/8 Cxc

Product Description

The NDL INDUSTRIES W1083 is a copper reducing coupling designed to transition between two different pipe sizes in a sweat-connect (C x C) configuration. This fitting accepts a 2-5/8-inch connection on one end and a 2-1/8-inch connection on the other, allowing a plumber or HVAC technician to step down copper line sizes within a system. It is constructed for use in copper piping systems where a direct solder joint is required. The C x C ends are prepared for standard flux-and-solder installation following accepted trade practice. This fitting is sold in box quantities and is suited for both commercial and residential applications.

This reducing coupling is used wherever a copper piping system requires a size transition between 2-5/8-inch and 2-1/8-inch nominal outside-diameter tubing. Typical applications include HVAC refrigerant line sets, hydronic systems, and plumbing distribution mains where copper is the specified material. Licensed plumbers and HVAC technicians performing rough-in, retrofit, or repair work are the primary installers. The fitting is stocked in box quantities of 12, making it practical for contractors handling multiple connections on a single job.

Key Features

• Reduces from 2-5/8 inches to 2-1/8 inches in a single fitting
• C x C (sweat) connection type on both ends — compatible with standard flux-and-solder technique
• Copper construction for corrosion resistance and long service life in wet systems
• Box quantity of 12 units supports multi-connection jobsite needs
• Manufactured by NDL Industries Inc. to OEM-style dimensional standards

Compatibility

Designed as an OEM-style replacement or new-installation fitting for copper piping systems requiring a sweat-connect reduction from 2-5/8 inches to 2-1/8 inches outside diameter.

Installation Notes

Installation is performed by a licensed plumber or HVAC technician using standard copper sweat-joint tools including a tubing cutter, emery cloth or fitting brush, lead-free flux, and a propane or MAP-gas torch. Shut off and depressurize the system completely and ensure the pipe is dry before applying heat, as residual moisture will prevent a sound solder joint. Follow applicable local plumbing codes and ASTM B88 tubing standards when selecting compatible copper tube. Do not use open flame near combustible materials without proper shielding.
