The NIBCO I018050 is an ABS plastic DWV trap fitting designed for drain, waste, and vent plumbing systems. It features a 1-1/2 inch Hub x Slip Joint (SJ) end connection configuration, making it compatible with standard DWV pipe assemblies in residential and light commercial applications. Molded from Acrylonitrile Butadiene Styrene (ABS), this trap operates across a wide temperature range from -40 degrees F to 180 degrees F. Licensed plumbers install this fitting during rough-in or service work on sink drains, lavatory drains, and similar DWV fixtures where a trap is required by code.
This fitting is suited for residential and light commercial drain, waste, and vent systems. The Hub x SJ connection style allows the hub end to receive pipe with solvent cement while the slip joint end accommodates mechanical assembly, giving installers flexibility during drain line assembly or repair. Typical applications include kitchen sinks, bathroom lavatories, and utility sink drain installations where a 1-1/2 inch trap is specified.
Designed as an OEM-style replacement and new-installation fitting for 1-1/2 inch residential and light commercial ABS DWV drain, waste, and vent systems.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and drain the line before beginning any trap work. Use approved ABS solvent cement on the hub connection and ensure the slip joint nut and washer are properly seated before tightening. Do not over-tighten the slip joint connection, as ABS fittings can crack under excessive mechanical force.
