GROCO Non-Metallic Strainer Cap Fits ARG-1000 & ARG-1250

The GROCO Non-Metallic Strainer Cap (ARG-1001-PC) is a replacement strainer cap designed for GROCO ARG-1000 and ARG-1250 seawater strainer assemblies—essential maintenance components for any serious boater running raw water cooling systems. After years on the water, you know that keeping your engine's raw water intake clean is non-negotiable; this cap protects the strainer basket while allowing you to service and inspect the mesh without replacing the entire assembly.

Whether you're cruising coastal waters or heading offshore, a functional strainer cap prevents debris accumulation that can restrict coolant flow and compromise engine performance. Constructed from durable non-metallic material, this strainer cap resists corrosion and galvanic action that would degrade brass or steel components in saltwater environments. The non-metallic design eliminates the risk of dissimilar metal corrosion while maintaining structural integrity under normal operating pressures.

At just 0.2 lbs and compact in dimensions (4 x 1 x 4 inches), the cap installs and removes quickly without requiring special tools, making routine strainer cleaning a straightforward dockside task rather than a trip to the yard. This replacement cap is ideal for boat owners and marine mechanics who maintain GROCO strainer systems on inboard and outboard cooling circuits. Direct compatibility with ARG-1000 and ARG-1250 housings ensures proper fit and reliable sealing without modification.
