The NIBCO INC T00210D is a 1/2 inch CPVC pipe cap designed to terminate the end of a CPVC supply line. It provides a secure, solvent-weld closure that prevents flow and maintains system pressure at open pipe ends. CPVC construction gives it chemical resistance and the ability to handle higher operating temperatures compared to standard PVC, making it a dependable fitting for hot and cold potable water systems. Licensed plumbers and pipefitters install this cap during new construction, remodels, and service work where a run must be capped off and pressure-tested.
This fitting is used in residential and light commercial plumbing applications where CPVC piping is the specified material. Common scenarios include capping unused branch outlets, isolating sections of a system for pressure testing, or permanently terminating a line that is no longer in service. The 1/2 inch size covers the most common residential water distribution line size. It is sold in a package quantity of 20, making it practical for stocking on a service vehicle or job site.
Designed as an OEM-style replacement and standard fitting for 1/2 inch CPVC piping systems in residential and light commercial plumbing applications.
Installation is performed by a licensed plumber following applicable local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before cutting and fitting. Clean and prime the pipe end before applying CPVC solvent cement to both the pipe and the cap socket. Allow full cure time per the cement manufacturer instructions before restoring system pressure.
