The ARG-756 fits all ARG series strainers manufactured from August 2001 onward and includes the wingnut and its O-ring as a matched set — ensuring a proper seal when reinstalled.\u003c\/p\u003e\u003cp\u003eThe drain wingnut is the small threaded plug at the base of the strainer body used to drain the strainer for winterization or service. The O-ring seats against the strainer body to prevent raw-water weeping at the drain point. Replacing both together is the correct practice — reusing an old O-ring on a new wingnut (or vice versa) risks a poor seal.\u003c\/p\u003e\u003ch3\u003eWhat’s Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDrain wingnut (1)\u003c\/li\u003e\n\u003cli\u003eDrain wingnut O-ring (1)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eGroco ARG series raw-water strainers manufactured August 2001 and newer\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest use case:\u003c\/strong\u003e The correct replacement when the drain wingnut is cracked, cross-threaded, or weeping at the base of the strainer body.
