GROCO Drain Plug with O-Ring for ARG Strainer - ARG-756

The GROCO Drain Plug with O-Ring (ARG-756) is a critical replacement part for maintaining the watertight seal of your raw water strainer. This specific wingnut-style plug is designed for modern GROCO ARG Series strainers and serves as a simple, tool-free solution for draining the unit during winterization or maintenance.

Critical Compatibility

The ARG-756 is specifically engineered for newer models. Using the wrong plug can lead to leaks or improper threading.

• Modern Models: Fits ARG style strainers manufactured after August 1, 2008.

• Older Models: If your strainer was built before 2008, you likely need the ARG-506 (old style) drain plug instead.

• Universal Fit: This single plug size is compatible across the entire ARG series range, including the ARG-500, ARG-750, ARG-1000, and up to ARG-3000 models.

Key Features

• Complete Kit: Includes both the non-metallic wingnut drain plug and the necessary O-ring to ensure a leak-proof seal.

• Tool-Free Design: The wingnut shape allows you to hand-tighten or remove the plug without needing wrenches, which is ideal for tight engine room spaces.

• Durable Materials: Made from high-quality, corrosion-resistant materials designed to withstand constant exposure to raw lake or seawater.

• Easy Maintenance: Replacing the O-ring and plug regularly prevents vacuum leaks that can cause your engine's cooling system to lose its prime.
