The NDL INDUSTRIES W4006 is a 5/8-inch copper standard tee fitting used in plumbing and HVAC piping systems where a branch connection is required. It features an all-copper construction with three sweat-solder (C x C x C) connections, making it compatible with standard copper tubing installations. This fitting is a direct, no-frills solution for splitting or branching a copper line in residential and light commercial applications. Licensed plumbers and HVAC technicians rely on this type of fitting when routing refrigerant lines, domestic water supply, or hydronic distribution piping.
The W4006 is suited for residential and commercial plumbing rough-in work as well as HVAC refrigerant or hydronic piping wherever a branch tee is required in 5/8-inch copper tubing runs. Its sweat-connection design means all three ports are soldered in place using standard copper joining practices. Sold in a box quantity of 50, this fitting is well-suited for contractors who need a reliable supply on active job sites.
Designed as an OEM-style replacement and standard-service fitting for 5/8-inch copper tubing in plumbing and HVAC piping systems using sweat-solder connections.
Installation should be performed by a licensed plumber or qualified HVAC technician following applicable IPC and IFGC codes. Shut off and depressurize the supply line before cutting into existing copper pipe. Clean all mating surfaces and apply flux prior to soldering; use lead-free solder where required by local code. Do not apply flame directly to adjacent fittings or previously soldered joints during installation.
