Oatey 1443SS Stainless Steel Basket Strainer 3.5-4 in

Product Description

The OATEY 1443SS is a cup-style basket strainer assembly built for kitchen sink drain openings ranging from 3.5 inches to 4 inches. Constructed from deep-drawn stainless steel with rolled threads, it provides lasting corrosion resistance in wet drain environments. The assembly ships complete with a lock nut and tailpiece nut, making it a ready-to-install replacement for standard kitchen sink applications. A spring steel clip closure seals the basket firmly in place, delivering a water-tight, leak-proof fit. Plumbers and experienced DIYers install this strainer as a direct drop-in replacement when the existing strainer body or basket has corroded, cracked, or begun leaking at the drain flange.

This strainer assembly is suited for residential kitchen sinks with standard 3.5-inch to 4-inch drain openings. The complete kit eliminates the need to source lock nuts or tailpiece nuts separately, making it well-suited for service calls where a fast, clean installation is the goal. The stainless steel body resists the moisture and detergent exposure common in kitchen drain environments, and the rolled thread design ensures consistent engagement with standard drain fittings.

Compatibility

Installation Notes

Installation is performed by a licensed plumber or qualified individual familiar with drain fitting procedures. Shut off the water supply and clear standing water from the sink before beginning work. Plumber's putty is typically applied under the strainer flange to seal against the sink basin. Do not overtighten the lock nut, as excessive force can crack the sink basin or distort the strainer body.
