GROCO BS-15 Stainless Steel Basket - 3.1" x 18.3"

The GROCO BS-15 Stainless Steel Basket is a marine-grade replacement filter element designed for raw water strainers on boats and water systems. This 3.1" x 18.3" basket serves a critical function in protecting engine cooling systems and potable water lines from debris, sediment, and salt-water corrosion. Whether you operate a sailboat, powerboat, or commercial water system, maintaining a clean strainer basket is essential for preventing costly engine damage and maintaining reliable water flow.

Constructed from 304 stainless steel, the BS-15 basket resists rust and corrosion inherent to saltwater and brackish environments where standard steel would fail rapidly. The basket features an improved handle design that simplifies removal and installation during routine maintenance cycles. Its 3.1-inch diameter and 18.3-inch length are engineered to maximize filtration surface area while maintaining low pressure drop across the strainer housing, ensuring optimal system performance without restricting water flow or creating excessive backpressure on your engine or pump.

The BS-15 basket is compatible with GROCO's ARG-3000 and 932-3000 raw water strainer models, making replacement straightforward during seasonal maintenance or after extended operation in high-debris environments. Boaters and marine technicians appreciate the stainless steel construction for its longevity in harsh conditions—it outlasts zinc-plated alternatives by years. Regular basket inspection and cleaning extend strainer life and protect vulnerable engine components. This basket is an economical preventive maintenance item that pays dividends in engine reliability and reduced corrosion-related downtime.
