GROCO BS-13 Stainless Steel Basket - 3.1" x 13.8"

The GROCO BS-13 Stainless Steel Basket is a premium replacement filter component designed for marine and industrial raw water strainer systems. Built for the ARG-3020 strainer model, this basket serves as the critical filtration element that protects seawater cooling systems, ballast intakes, and engine cooling circuits from sediment, debris, and contaminants. Marine professionals and boat owners rely on GROCO's engineered baskets to maintain system integrity and prevent costly equipment damage in saltwater and brackish environments.

Manufactured from 304 stainless steel, the BS-13 basket resists corrosion and oxidation in harsh marine conditions while maintaining structural durability through repeated cleaning cycles. The basket measures 3.1 inches in diameter by 13.8 inches in length, providing optimal surface area for high-flow filtration without excessive pressure drop across the strainer bowl. An improved handle design—a hallmark of GROCO's engineering—allows for easier removal and installation during routine maintenance, reducing downtime and service labor costs. The 304 stainless steel construction ensures decades of reliable service in saltwater, freshwater, and mixed-use applications.

This replacement basket is essential for ARG-3020 strainer users who require reliable raw water filtration for marine engines, thermal management, and water intake systems. Routine basket replacement maintains peak strainer performance and prevents the accumulation of debris that can compromise water flow or damage downstream equipment. Installation is straightforward—simply remove the strainer bowl, lift out the spent basket using the reinforced handle, rinse and inspect the bowl, and insert the new BS-13 basket. For boat builders, marine mechanics, and facility managers operating GROCO filtration systems, maintaining spare baskets on hand ensures minimal operational interruption.
