Brizo 69050-pn Kitchen Sink Flange and Strainer

Product Description

The BRIZO 69050-pn is a kitchen sink flange and strainer assembly designed for top-mount installation in standard 3.5-inch sink drain openings. The unit features a polypropylene drain housing paired with a brass strainer and basket, combining corrosion-resistant materials in a two-component drain assembly. The 4.5-inch diameter brass flange provides a secure, finished seal at the sink deck. Thread engagement is handled through 1.5-inch x 11.5-inch NPSM threads, allowing connection to standard drain tailpieces and trap assemblies. This part is installed by licensed plumbers and experienced plumbing contractors during kitchen sink rough-in or fixture replacement.

This flange and strainer assembly is suited for residential and light commercial kitchen sink installations where a top-mount drain fitting is required. It fits sink cutouts sized to the standard 3.5-inch drain opening found in the majority of drop-in and undermount kitchen sink configurations. The brass strainer and basket provide durability under daily use, while the polypropylene housing resists chemical exposure common in kitchen drain environments.

Installation Notes

Installation is performed by a licensed plumber. Shut off the water supply and ensure the drain line is clear before beginning work. Plumber's putty or a silicone sealant is typically applied under the flange before seating; follow the fixture manufacturer's recommendation for sealant type. Verify NPSM thread engagement is complete and watertight before restoring service and testing for leaks.
