Product description

This replacement piston disc is a critical internal component found within the pneumatic cylinders of Snap-On tire changers, most commonly in the bead breaker assembly. The disc serves as a structural support for the piston seal, ensuring that air pressure is distributed evenly across the entire piston face to maximize force. Under the extreme pressures required to break the bead of a stiff tire, the disc can suffer from fatigue, cracking, or warping. A compromised piston disc can lead to seal bypass or mechanical binding within the cylinder, resulting in a loss of power or erratic movement. Replacing a damaged disc during a cylinder rebuild is essential for restoring the machine's original bead-breaking performance.

Product highlights

• Robust structural design provides a stable platform for high-pressure pneumatic seals.
• Precision-balanced geometry ensures smooth travel within the cylinder bore.
• Heavy-duty material resists deformation under peak pneumatic load cycles.
• Direct replacement for internal cylinder components on professional Snap-On machines.
