Upper 1" Waterway air venturi control seal. Suits most Waterway 1" air controls such as 660-3587, 660-3570, 660-3560 and is inserted below the internal valve above the check ball. 

These rubber seals can fail and replacement means the air venturi control doesn't need to be completely replaced. 

Older air controls may have been fitted with a flat gasket seal with 'dove tail' outer shape. This replacement seal CANNOT replace that seal type. 

Outside diameter 32mm.
