Oatey 2431NPC Kitchen Basket Strainer 3.5 Inch Ss

Product Description

The OATEY 2431NPC is a kitchen basket strainer assembly designed for standard 3.5-inch sink drain openings. The unit features a solid brass body with deep-cut threads for a secure, leak-resistant connection. The basket itself is rust-proof stainless steel with a safety rolled edge, reducing the risk of cuts during cleaning or removal. A polished chrome finish over the zinc die cast post gives the assembly a clean, finished appearance. This strainer is installed by licensed plumbers and experienced DIYers during sink replacements, kitchen remodels, or drain repair work.

This basket strainer fits standard kitchen sinks with a 3.5-inch drain hole and accepts a 4.5-inch diameter flange seat. The assembly includes a fiber washer for the sink body seal and a polyethylene flanged tailpiece washer for the drain connection below. It is suited for residential kitchen sink installations where a durable, corrosion-resistant drain fitting is required. The chrome-plated finish integrates with standard kitchen fixture hardware.

Installation Notes

Installation is typically performed by a licensed plumber or qualified DIYer following IPC guidelines. Shut off the water supply and clear the cabinet below the sink before beginning work. Apply plumber's putty under the flange before seating it in the drain opening, and hand-tighten the locknut before final snugging to avoid cracking the sink basin. Do not over-torque the locknut on cast iron or porcelain sinks.
