Oatey K22050 Basket Strainer Stopper 3-3/8 in Stainless Steel

Product Description

The OATEY K22050 is a spring action post basket strainer stopper designed to create a tight water seal in sink drain assemblies. Constructed from stainless steel, it measures 3-3/8 inches in diameter and seats securely into compatible basket strainer bodies. The spring action post mechanism allows the stopper to lock into the closed position under water pressure and release with a simple push, making it a straightforward field replacement for worn or damaged stoppers. Plumbers and drain service technicians install this part during routine sink drain maintenance or when an existing stopper fails to hold water.

This stopper is suited for residential and light commercial kitchen or utility sink applications where a basket strainer assembly is already installed. It is a direct drop-in replacement for select Watts Brass and Tubular basket strainer models, making it a practical service part to carry on a service vehicle. Installation requires no special tools and takes only minutes when the correct compatible strainer body is present.

Installation Notes

Installation is performed by a licensed plumber or qualified drain technician. Shut off the water supply and drain any standing water from the sink before servicing the strainer assembly. The stopper seats directly into the existing strainer body — no adhesives, tools, or sealants are required. Verify the strainer body model number before installation to confirm fit.
