Plunger / Piston
This is the replacement plunger / piston that is located inside the bead breaker cylinder. Two giant wiper seals encase the aluminum plunger. Signs of failure is during activation the shaft will move the arm slowly or not at all. Water is a major cause of failure as the water deteriorates the metal.
The plunger has a diameter of 186mm / 7-1/4″. The inside diameter where the shaft is threaded on is 20mm. The seals are included with the plunger. This plunger can also fit many Chinese made machines as they copied a lot of the Italians.
We also carry the entire cylinder.
