Nibco Inc W01875D Copper Tube End Cap 1.5 Inches

Product Description

The NIBCO INC W01875D is a lead-free copper tube end cap designed to seal the open end of copper pipe or tubing. It uses a standard sweat solder cup connection, making it a straightforward, reliable solution for permanently closing off a line. Sized for 1.5-inch copper tube (C-size), it fits over the pipe end and is soldered in place using conventional soft-solder technique. Plumbers and pipefitters install this fitting in both new construction and retrofit work where a branch or run needs to be capped and pressure-tested or left sealed.

This end cap is suited for residential and light commercial plumbing systems where copper sweat fittings are the standard. Typical applications include sealing unused branch lines, capping off stub-outs, and closing supply lines during phased construction. The lead-free construction meets current potable water requirements, making it appropriate for domestic water systems. It is sold in a package quantity of 25 units, making it a practical stocking item for service trucks and shop inventory.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters using standard soft-solder technique per applicable IPC and local plumbing code requirements. Shut off and depressurize the water line and drain the pipe thoroughly before soldering, as moisture in the pipe will prevent a sound joint. Clean the pipe end and fitting cup with emery cloth and apply flux before heating. Do not overheat the fitting, as excessive heat can damage adjacent fittings or compromise the joint.
