The DURA PLASTIC 429-080BC is an 8-inch nominal PVC pipe cap designed to terminate or seal the end of a Schedule 40 PVC piping system. Built with a socket end style, it slips over the pipe end and is solvent-welded in place to create a pressure-rated, watertight seal. This cap is domestically manufactured and suited for use in water distribution, irrigation, pool and spa plumbing, and industrial fluid handling systems. Licensed plumbers and pipefitters are the typical installers, though experienced pool and irrigation contractors also work with this fitting regularly.
This cap fits Schedule 40 PVC pipe at 8-inch nominal sizing and is appropriate for both residential and commercial plumbing applications. Its socket end configuration makes it compatible with standard solvent-cement joining methods used throughout the trade. Common uses include capping off unused branch lines, pressure-testing pipe runs, and permanently terminating piping during system modifications or shutdowns.
Designed as an OEM-style replacement and standard fitting for Schedule 40 PVC piping systems at 8-inch nominal pipe size.
Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and ASTM standards for solvent-welded PVC fittings. Depressurize and drain the piping system fully before cutting in or capping any line. Use an approved PVC primer and solvent cement rated for Schedule 40 pipe, and allow full cure time before returning the system to service. Do not apply heat or use threaded connections on socket-style fittings.
