Sch 40 PVC Cap 4 in. Socket

Built for dependable pipe-end closure, the Sch 40 PVC Cap 4 in. Socket helps seal the end of a 4 in. Schedule 40 PVC piping run with a clean, solvent-weld socket connection. Made from white PVC for Schedule 40 systems, this cap supports long-lasting performance in compatible water and fluid applications while resisting rust, scale, pitting, corrosion, and many chemicals better than metal fittings. Its smooth PVC construction helps maintain efficient flow conditions, while the lightweight design makes handling and installation easier on the jobsite. The 4 in. cap is listed in the PDF as part number 447-040, with a socket hub outside diameter of 5-1/16 in., height of 3-1/8 in., and approximate weight of 0.79 lb.; the PDF also notes Schedule 40 PVC fittings are designed to ASTM D 2466 and PVC Type I cell classification 12454, with NSF certification for potable water service where specified. This cap provides a simple, reliable way to close pipe ends while supporting a durable Schedule 40 PVC system.
