Nibco Inc W01860T Copper Tube Cap 0.75 in Solder Cup

Product Description

The NIBCO INC W01860T is a lead-free copper tube cap designed to seal the open end of a copper pipe or tube. It uses a solder cup connection method, allowing the fitting to slip over the pipe end and be sweated in place with standard soldering techniques. This cap is suited for plumbing, hydronic, and mechanical piping systems where a branch or run must be permanently closed off. At 0.75 inches, it fits standard three-quarter-inch copper tube and is sold in packs of 25, making it practical for contractor stocking and service work.

This fitting is used in residential and light commercial plumbing applications where a copper pipe end requires a clean, pressure-rated termination. Common install scenarios include capping unused branch connections, decommissioning service lines, or closing rough-in stubs during phased construction. The lead-free construction meets federal and state potable water requirements, making it appropriate for use in drinking water systems as well as general plumbing piping.
