Their purpose is to protect the rod seal from contaminants as well as to apply a hydraulic load to the u-cup. Some of these urethane rings are used as a backup ring combined with a rubber sealing ring in suspension cylinder applications. Part numbers starting with a G are used in Case® equipment; the others are typically used in Caterpillar® equipment. Temperature: -40°F to 225°F Pressure: 0 to 5000 psi
