Oatey 1431SSBX Basket Strainer Fixed Post 3-1/2 Inch

Product Description

The OATEY 1431SSBX is a fixed-post basket strainer designed for kitchen sink drain openings with a 3-1/2 inch diameter. The body is constructed from stainless steel with cut threads for a secure, leak-resistant fit. The slip nut is die cast, and the basket features a rolled edge with a chrome-plated plastic fixed stick post. This strainer is a direct replacement-style fitting installed by licensed plumbers and experienced DIYers during sink installations, drain replacements, or kitchen remodels.

This basket strainer is suited for residential kitchen sink applications where a standard 3-1/2 inch drain opening is present. It is typically installed when replacing a worn or leaking strainer body, upgrading to a stainless steel finish, or during a full sink and drain rough-in. The fixed post design keeps the basket seated during normal use. Each unit is sold individually, one per box.

Installation Notes

Installation is typically performed by a licensed plumber or qualified tradesperson during sink drain service. Shut off the water supply and clear standing water from the sink before beginning work. Plumber's putty is commonly applied under the strainer flange to create a watertight seal against the sink basin. Follow applicable IPC and local plumbing code requirements for drain fitting installation.
