The 9999100855 ORFS seal kit consists of components used to maintain the seal and integrity of hydraulic connections in high-pressure systems. These seals prevent fluid loss within the machine's hydraulic circuits, which is necessary for maintaining consistent system pressure and operational efficiency across various crane functions.
This kit is compatible with the Grove RT 890 rough-terrain crane. It is applied to hydraulic lines associated with the boom, outriggers, cylinders, and pumps where constant pressure and vibration are present. The kit includes O-rings and backup components designed to fit ORFS (O-Ring Face Seal) connection standards.
ORFS seals function by compressing an elastomeric O-ring against a flat face, creating a tight seal that resists leakage in hydraulic systems. This type of connection is commonly used in heavy machinery to provide a secure junction for hoses and tubes that are subject to pressure cycles and mechanical movement.
