O-ring for Clark 13HR28361 -1

The 25K40404 O-ring serves as a sealing component within the hydraulic or transmission systems of Clark machinery. It creates a barrier between two mating surfaces to prevent the escape of fluids such as oils or lubricants and to block the entry of external contaminants. By maintaining a tight seal, this component helps preserve the operating pressure required for the proper function of valves, cylinders, and hose connections.

This part is compatible with the Clark 13HR28361 -1 model. It is designed to fit into specific grooves where its circular cross-section deforms under compression to fill gaps and establish a seal. Proper installation ensures that the hydraulic or mechanical system remains closed, preventing fluid loss and protecting internal components from environmental exposure.

O-rings are used throughout heavy machinery to provide static or dynamic seals in fluid power circuits. They are selected based on their ability to withstand the specific pressures and temperatures encountered within the assembly. Regular inspection and replacement of these seals are standard maintenance practices to ensure that hydraulic systems operate without pressure drops or external leakage.
