Groco ARG-750-S Bronze Raw-Water Strainer — 3/4" Hose | #304 SS Basket
Protect your raw-water cooling and washdown systems from debris with this heavy-duty bronze strainer sized for 3/4" hose connections. The Groco ARG-750-S filters out weed, grit, and shell fragments before they reach your engine heat exchanger, generator, air conditioning system, or other raw-water equipment — keeping impellers and heat exchangers running clean.
The see-through screw-on cap lets you check basket condition at a glance without tools, and the quick-release mounting system means cleaning takes seconds. O-ring seals at the cap and between the strainer head and sight glass keep the system tight under both pressure and vacuum, with no tie rods to work loose over time.

Parts Desk Insights
Best use case: A common fit for smaller auxiliary engines, outboard-powered boats with raw-water cooling, and compact generator installations where 3/4" intake lines are standard. If your hose size differs, the ARG series covers the full range: ARG-500-S (1/2"), ARG-1000-S (1"), ARG-1250-S (1-1/4"), ARG-1500-S (1-1/2"), ARG-2000-S (2"), and ARG-2500-S (2-1/2"). For routine maintenance, the GROCO ARG-1 Service Kit covers the ARG-750-S with replacement O-rings and drain wingnut gasket. For the drain wingnut alone, see the ARG-756 Drain Wingnut & O-Ring (August 2001 & newer) or the ARG-506 (pre-August 2001).
