Waterco HydroStorm Lock Ring is a replacement lock ring for compatible Waterco HydroStorm sand filter applications. The lock ring helps secure the filter’s serviceable upper assembly so the tank and valve or lid connection remain properly retained during operation. This part is commonly replaced when the original ring is cracked, worn, difficult to tighten, damaged during service, or no longer holding the connection as intended. Because filter pressure vessels require correct retention hardware, confirm the HydroStorm model, tank style, and part number 61209 before ordering. Do not operate a pressurized filter with damaged or mismatched clamp or lock components.
