The DURA PLASTIC 416-040 is a 4-inch nominal Schedule 40 PVC coupling with socket end connections, designed for joining sections of PVC pipe in pressurized and non-pressurized piping systems. Manufactured domestically, this standard coupling is a common component in residential and commercial plumbing, irrigation, pool and spa circulation, and industrial fluid handling. The socket end style allows for solvent-weld assembly, creating a leak-free joint when properly primed and cemented. Licensed plumbers, pipefitters, and pool service technicians install this type of fitting as part of new construction or repair work on Schedule 40 PVC piping networks.
The 416-040 is suited for 4-inch Schedule 40 PVC pipe installations across a range of applications including pool and spa plumbing, potable water distribution, irrigation mains, and general-purpose fluid conveyance. Its socket end configuration is compatible with standard solvent-weld assembly procedures used throughout the trade. Domestic manufacture supports projects where U.S.-sourced materials are required or preferred by specification.
Designed as an OEM-style replacement and standard fitting for 4-inch Schedule 40 PVC piping systems used in plumbing, pool, irrigation, and industrial fluid handling applications.
Installation is performed by licensed plumbers, pipefitters, or qualified pool and spa technicians. Shut off flow and relieve system pressure before cutting into an existing line. Clean and dry pipe ends before applying PVC primer and solvent cement per manufacturer instructions and applicable IPC or local plumbing code requirements. Allow full cure time before restoring system pressure.
