A Piston Wear Ring also known as a guide ring is designed to minimize friction and guide the cylindrical rod along the cylinder's inner surface. It is made from plastic and helps reduce leakage, maintain efficiency, and prevent metal-to-metal contact between the moving parts.Attributes:• Helps to dampen the vibrations caused by the movements• Features a slit cut on the Backup Ring which helps equalize the pressure buildup on the primary sealing element Applications:A Piston Wear Ring is used to ensure smooth operation by absorbing the radial load acting on the rod.
