Collection: Strainers & Baskets

Raw water strainers protect your engine cooling system, air conditioning, and livewell plumbing by catching debris before it reaches pumps and heat exchangers. The core decision is sizing: pipe diameter must match your through-hull or seacock, and GROCO covers the most common sizes from 3/4" up to 2-1/2". For high-flow applications or larger vessels, the ARG-2500 series strainers from GROCO offer a choice of basket material, including stainless steel, non-metallic, and Monel, each suited to different water conditions and budgets. Johnson Pump units are available in 20 mesh or 40 mesh, where finer mesh catches smaller particles but requires more frequent cleaning in weedy or silty anchorages.

If you are replacing worn components rather than installing a complete new system, check whether a drop-in basket, such as the Raritan replacement basket or GROCO ARG-2500 series baskets, fits your existing housing before purchasing. GROCO also sells combination ball valve and strainer assemblies that simplify installation where space is tight. Authorized dealer stock here means you are getting genuine parts with full manufacturer warranty coverage.
