Oatey 1443-1SS Stainless Steel Basket Strainer Stopper

Product Description

The OATEY 1443-1SS is a replacement basket strainer stopper designed for use with compatible sink drain strainer assemblies. Constructed from stainless steel with a chrome-plated brass knob, this stopper provides a corrosion-resistant seal for kitchen or utility sink drain baskets. A 1-3/4 inch spring steel clip secures the stopper in the closed position, holding it firmly against the strainer body to block drainage when needed. Licensed plumbers and skilled DIYers install this as a direct service replacement when an existing stopper is lost, worn, or damaged, restoring full open-and-close function without replacing the entire strainer assembly.

This stopper is suited for residential kitchen and utility sink applications where a basket strainer assembly is already installed. It is specifically noted as a replacement stopper for the Watts Brass and Tubular basket strainer model 644003. The stainless steel construction and spring clip design are standard across a wide range of residential sink drain configurations, making this a commonly stocked service part for plumbing contractors and maintenance technicians.

Installation Notes

Installation is typically performed by a licensed plumber or experienced DIYer and requires no special tools beyond hand access to the sink drain area. Shut off water supply and clear the sink basin before servicing the drain assembly.
