GROCO Non-Metallic Strainer Cap Fits ARG-500 & ARG-750

The GROCO Non-Metallic Strainer Cap Fits ARG-500 & ARG-750 is a reliable replacement component designed for marine water systems that rely on raw water intake strainers. This strainer cap serves as a critical access point and protective cover for GROCO's ARG-series raw water strainers, commonly installed on vessels, RVs, and watercraft requiring dependable saltwater or freshwater filtration. Whether you're maintaining an existing system or performing routine component replacement, this non-metallic strainer cap ensures your water intake remains properly sealed and protected from debris and contamination.

Constructed from non-metallic polymer material, this strainer cap resists corrosion in harsh marine environments where traditional metal components would degrade rapidly. The non-metallic construction eliminates galvanic corrosion concerns common in saltwater applications, extending component lifespan significantly. Engineered to fit both ARG-500 and ARG-750 strainer models, this cap maintains a secure seal at the strainer head while allowing straightforward access for periodic basket cleaning and maintenance. The compact 3 x 1 x 3 inch design integrates seamlessly into tight engine compartments and raw water system installations.

Boat owners, marine mechanics, and RV technicians benefit from keeping this replacement cap on hand for preventive maintenance programs. Installation is straightforward—simply unscrew the existing cap and thread this replacement component clockwise onto the ARG-500 or ARG-750 strainer body. Compatible with both duplex and simplex raw water strainer configurations, this part is essential for systems operating in saltwater, brackish, or debris-laden freshwater environments. Check your existing GROCO strainer model number to confirm compatibility before ordering this affordable replacement component.
