Fits These Clack Control Valve Models
This V3180 O-ring is designed for Clack WS1 control valves and 1.25-inch valve configurations. It seals the connection between the tank opening and the valve body on top-mount softener and filter systems. Also used in Clack 1190 head assemblies and the newer D1220/D1400 valve models for both inlet and outlet ports. If you're servicing a Clack WS1 system or upgrading to a D1400 head, this is your primary tank seal.
When to Replace This O-Ring
Control Valve Service
Replace whenever you disassemble the valve head or remove the control valve from the tank.
Tank-to-Valve Junction
If you see water seeping from the base of the valve where it meets the tank threads, replace immediately.
Preventive Replacement
Even without visible leaks, elastomer O-rings harden over time and should be replaced during routine service.
OEM Quality
Factory-spec dimensions for Clack valves, not a generic aftermarket substitute.
Prevents Tank Leaks
Maintains water-tight seal under system pressure and during regeneration cycles.
Keep a Spare
Inexpensive insurance part to have on hand for emergency valve repairs.
