CAT Dump Truck Rod Seal 2G-9491 2G9494 Hydraulic Cylinder Seal Kit

This CAT rod seal is made of high-quality oil-resistant rubber/polyurethane material, suitable for the rod part of hydraulic cylinders, lifting cylinders or suspension cylinders of CAT mining dump trucks. The lip is precision processed to form a tight fit with the piston rod, maintaining stable sealing under high pressure and high-frequency reciprocating motion, effectively reducing hydraulic oil leakage and maintaining system working pressure. The seal features excellent wear resistance, aging resistance, and high/low temperature resistance, adapting to the harsh dust, humidity and temperature difference environment in mines. It is not easy to deform or crack after long-term use, greatly reducing cylinder maintenance frequency. Part number 2G-9491 (2G9494) is the original standard specification, with installation dimensions completely matching the original parts for direct replacement without additional processing, a core accessory to ensure stable operation of the hydraulic system.
