Piston seal for Grove TM875

The piston seal 945112 functions as a barrier between the piston and the inner wall of a hydraulic cylinder. By creating a seal, it allows hydraulic pressure to act effectively on the piston to generate the force required for machine movement. This component is designed to prevent internal fluid bypass, which ensures the cylinder maintains its load-bearing capacity and operational precision during use.

This part is compatible with the Grove TM875 truck-mounted crane. It is used within the hydraulic systems responsible for lifting, extension, and stabilization functions on this specific model. Proper installation of this seal helps maintain the pressure levels necessary for the crane to position loads accurately and safely.

Piston seals of this type are used in hydraulic cylinders to separate the high-pressure and low-pressure sides of the piston. Their primary role is to ensure that hydraulic energy is converted into mechanical force without loss of fluid volume. When a seal is properly fitted, it prevents internal leakage that would otherwise cause the cylinder to drift or lose power under load.
