GROCO ARG-500 Series 1/2" Raw Water Strainer w/Stainless Steel Basket

The GROCO ARG-500 Series 1/2" Raw Water Strainer with Stainless Steel Basket is an essential through-hull component for any serious cruising vessel, fishing boat, or extended-range offshore platform. This strainer is designed to protect your engine cooling circuit from debris, sediment, and marine growth that can clog your heat exchanger and lead to engine failure.

Constructed by GROCO, a trusted name in marine equipment, the ARG-500 features a durable stainless steel basket that resists corrosion in saltwater and brackish environments. The strainer is designed to maximize flow area and debris holding capacity, ensuring less frequent servicing without compromising cooling performance. Its robust cast design is rated for the pressure cycles of continuous engine operation.

Ideal for diesel auxiliaries on sailboats, inboard powerboat engines, or fishing vessels' raw water loops, this strainer is built to withstand years of exposure to salt spray and thermal cycling. Installation is straightforward, requiring only a single through-hull fitting and standard marine-grade hose clamps for a secure connection.
