Bsc Preferred LK335 Drain Fitting 3.5 Inch Stainless Steel

Product Description

The BSC PREFERRED LK335 is a 3.5-inch sink drain fitting constructed from Type 316 stainless steel. It includes a rubber seal that creates a watertight connection at the sink basin and a 1.5-inch O.D. by 4-inch tailpiece for connecting to the drain line below. Type 316 stainless steel offers strong resistance to corrosion and is well-suited for wet, high-use environments. This drain fitting is installed by licensed plumbers or experienced tradespeople in commercial and residential applications where a reliable, leak-free drain connection is required.

The LK335 is suited for use in commercial kitchens, prep sinks, bar sinks, and laundry room applications. The 3.5-inch drain opening size is a standard dimension for kitchen and utility sinks. The included 1.5-inch O.D. tailpiece connects to standard 1.5-inch drain line fittings without the need for additional adapters in most installations. The rubber seal compresses against the underside of the sink to prevent leaks at the drain basket seat.
