LEV VALVE PART, O-RING FRONT MOUNTING BLOCK, 3.0 & 4.5 VALVE (QUANTITY/30)
This thicker O-Ring fits between the valve and the mounting block. It’s the same O-Ring for the syrup and soda side. Always use warm water when inserting. This will avoid scarring and leakage. It is recommended to replace front mounting block o-rings every 5 years due to constant usage of the dispensing valves.
