The Cylinder Head Backup Ring creates a physical barrier that prevents the cylinder head gasket from being extruded or displaced under the extreme forces acting on the cylinder head. It is made of durable materials like plastic to withstand the impacts during the operation. By distributing these forces and maintaining the gasket's shape and integrity, the backup ring ensures a reliable and long-lasting seal, preventing fluid leaks. Attributes:• Withstand high pressures without deformation • prevent the cylinder head gasket from being dislodged or damaged by intense vibrations Applications:The Cylinder Head Backup Ring is used in boom cylinder and stick cylinder. It prevents the cylinder head gasket from being extruded or displaced, maintaining the seal's effectiveness. Maintain its structural integrity and sealing performance at elevated temperatures.
