GROCO ARG-1003 Sight Glass for ARG-1000 Strainers

The GROCO ARG-1003 Sight Glass for ARG-1000 Strainers is a replacement transparent housing component for the compatible GROCO ARG-series raw-water strainer identified in the product name. It restores the clear viewing section that lets operators inspect basket condition and debris accumulation without opening the strainer.

Correct model matching is essential because ARG strainer sizes use different sight-glass dimensions and sealing interfaces. Replacing a damaged or clouded viewing section can restore visibility while allowing the bronze head, cap, and other serviceable components to remain installed.

Verify the exact ARG strainer model before ordering and inspect the associated O-rings or seals during replacement. Isolate and drain the raw-water circuit, clean all sealing surfaces, reassemble according to GROCO instructions, and pressure-test the strainer for leaks before returning the system to service. See the rest of our bilge and water pumps.

• The replacement housing lets the operator see basket condition and debris.
• Replacing the sight glass avoids unnecessary replacement of the complete assembly.
• Model-specific dimensions preserve intended fit and sealing.
• Seal inspection during service helps maintain a leak-resistant water path.
