The NDL INDUSTRIES W3030 is a 45-degree copper sweat elbow designed to change flow direction in copper piping systems. Sized at 3/4 inches with a copper-to-copper (C x C) connection on both ends, it joins to copper tubing using standard solder or braze methods. This fitting is used in residential and light commercial plumbing, hydronic heating, and refrigeration piping where a 45-degree directional change is required. Licensed plumbers and pipefitters install this type of fitting as part of roughed-in or retrofit copper piping work.
The W3030 is suited for potable water supply lines, drain and vent rough-in applications, and hydronic heating loops where copper is the specified pipe material. The C x C end configuration means both sides accept copper pipe for soldered joints. It is sold in box quantities of 50, making it appropriate for plumbing contractors stocking for new construction or service work.
Designed as an OEM-style replacement and new-installation fitting for 3/4-inch copper piping systems using C x C sweat connections.
Installation is performed by a licensed plumber using standard copper sweat techniques. Shut off the water supply and fully depressurize and drain the line before cutting or soldering. Clean all mating surfaces with emery cloth and apply flux before soldering per ASTM B32 solder alloy requirements and local plumbing code. Do not apply heat to a pressurized or water-filled line.
