Ndl Industries W4041 Copper Reducing Tee 7/8x5/8x7/8 Cxcxc

Product Description

The NDL INDUSTRIES W4041 is a copper reducing tee fitting designed for use in refrigeration, HVAC, and plumbing piping systems. It connects three copper lines using a sweat (C x C x C) connection on all three ports. The run measures 7/8 inches on both ends, while the branch reduces to 5/8 inches, allowing a single inline run to feed a smaller branch line without additional adapters. Licensed plumbers and HVAC technicians typically install this fitting during new construction or service work where a branch takeoff is needed at a reduced size.

This reducing tee suits residential and light commercial copper piping installations where a 7/8-inch main run requires a 5/8-inch branch outlet. Typical applications include refrigerant line sets, hydronic heating loops, and domestic water distribution systems. The all-copper sweat construction keeps the fitting compatible with standard torch-and-solder installation practices common across plumbing and refrigeration trades.

Key Features

• Reducing branch outlet: 7/8-inch run x 7/8-inch run x 5/8-inch branch
• C x C x C sweat connection on all three ports
• Copper construction for reliable, corrosion-resistant performance in wet and refrigerant environments
• No additional adapters needed to step down branch line size
• Compatible with standard torch-and-solder installation methods

Compatibility

Designed as an OEM-style replacement or new-installation fitting for copper piping systems requiring a 7/8-inch x 5/8-inch x 7/8-inch reducing tee with sweat connections.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician in accordance with applicable local codes, IPC, or IFGC guidelines. Shut off and depressurize the line completely before cutting into existing piping. Clean and flux all joint surfaces thoroughly before applying heat; avoid overheating the fitting, as excessive heat can compromise the joint integrity. Allow solder joints to cool fully before restoring pressure to the system.
