GROCO ARG-500 Series 1/2" Raw Water Strainer w/Non-Metallic Plastic Basket

The GROCO ARG-500 Series 1/2" Raw Water Strainer with Non-Metallic Plastic Basket is a marine-grade intake protection system designed for serious boaters and anglers who demand reliability in saltwater and freshwater environments. This strainer is essential for anyone running a marine engine with raw water cooling, as it protects against fouled intakes caused by debris like seaweed, sand, and shells.

Built around GROCO's proven ARG-500 platform, this unit features a non-metallic plastic basket that resists corrosion in harsh marine environments. The 1/2" NPT port size ensures compatibility with standard through-hull fittings, delivering adequate flow while maintaining effective filtration. The design allows for rapid basket inspection and cleaning without disassembling the entire system, which is critical when you're miles offshore.

This strainer is suitable for fiberglass cruisers, aluminum workboats, and high-performance center consoles that rely on raw water cooling systems. Its plastic construction eliminates galvanic corrosion risks and integrates seamlessly with both metal and composite piping common in modern marine installations. Whether you're cruising coastal flats or navigating inland systems, this strainer provides peace of mind for your marine engine.
