Oatey dear-18bn Deep Locking Cup Sink Basket Strainer

Product Description

The OATEY dear-18bn is a sink basket strainer featuring a deep locking cup design and brass nuts for secure, leak-resistant installation. Part of the Dearborn Brass line, this strainer fits standard kitchen sink drain openings and provides a removable basket to catch food debris and prevent drain clogs. The brass nut construction resists corrosion and delivers long-term durability in demanding plumbing environments. Licensed plumbers and experienced DIYers install this type of strainer during sink replacements, remodels, or routine drain hardware upgrades.

This strainer is suited for residential and commercial kitchen sink applications. The deep locking cup design provides a positive seal when the basket is engaged, reducing the chance of unintended drainage during sink filling. It is a common replacement item in both new construction rough-in and service work where original drain hardware has worn, corroded, or failed to seal properly.

Installation Notes

Installation is typically performed by a licensed plumber or qualified tradesperson following IPC guidelines. Shut off water supply and clear standing water from the sink before beginning work. Use plumber's putty or the gasket supplied to create a watertight seal between the strainer body and the sink deck. Avoid over-tightening the brass nuts, as this can crack the sink flange or distort the sealing surface.
