GROCO ARG-755 Series 3/4 inch Raw Water Strainer with Monel Basket - ARG-755

The GROCO ARG-755 Raw Water Strainer (ARG-755) is a compact, high-efficiency 3/4" NPT filtration system specifically designed for smaller marine engines, generators, and air conditioning units. This particular model comes equipped with a Monel basket, which is the premium choice for boaters in harsh saltwater environments due to its superior resistance to pitting and corrosion.

Compact Powerhouse

The ARG-755 is essentially a "short" version of the ARG-750, providing the same pipe size in a smaller footprint (6.125" height) for installations where vertical clearance is limited.

• Monel Filter Basket: Offers the highest level of corrosion resistance, outperforming standard stainless steel in tropical and high-salinity waters.

• Tie-Rod-Free Design: Like the rest of the ARG series, it features a one-piece molded sight glass that eliminates traditional leak points, gaskets, and rods.

• Magnifying Cap: The non-metallic screw-on cap features a clear design that magnifies the internal view, allowing you to inspect the basket for debris without opening the unit.

• Tool-Free Servicing: Includes a quick-release mounting strap and a spin-off cap for maintenance without tools, making it easy to clear debris while underway.

Maintenance & Setup

Because this is a modern ARG unit, it uses the ARG-756 Drain Plug for seasonal winterization. If you are fitting out a smaller engine room, this compact unit pairs well with the S100 Wireless Remote or i70s Instrument for localized system monitoring.
