Nibco I175001 Dwv End Cap 1-1/4 in Hub Abs

Product Description

The NIBCO I175001 is a drain, waste, and vent (DWV) end cap fitting manufactured from acrylonitrile butadiene styrene (ABS) plastic. It terminates a 1-1/4 inch DWV pipe run with a hub-style connection, providing a clean, permanent seal at the end of a drain or vent line. The fitting is rated for a maximum working temperature of 180 degrees F and a minimum working temperature of -40 degrees F, making it suitable for standard interior plumbing environments. Plumbers and pipefitters install this fitting during rough-in and finish plumbing work on residential and light commercial drain systems.

This end cap is used to cap off DWV branch lines, stub-outs, or vent terminations in residential and light commercial plumbing systems. Typical applications include capping unused branch tees, terminating test plugs during pressure testing, and closing off vent lines that will not be extended. The hub end accepts 1-1/4 inch ABS pipe and is solvent-welded in place per standard ABS joining procedures.

Installation Notes

Installation is performed by a licensed plumber following applicable local plumbing codes and IPC or UPC requirements for ABS DWV systems. Shut off water supply and ensure the pipe section is dry and depressurized before joining. Clean and dry the pipe end, apply ABS solvent cement to both the pipe and the hub socket, and seat firmly with a quarter-turn per manufacturer instructions. Allow adequate cure time before pressurizing or backfilling.
