A hydraulic pump gasket is a component that is designed to create a seal between the hydraulic pump and the engine block. This gasket is made of high-quality materials that are resistant to heat, pressure, and other environmental factors. The primary function of this gasket is to prevent hydraulic fluid from leaking out of the pump and onto other parts of the engine. If the gasket becomes worn or damaged, it can cause leaks which can lead to reduced performance or even damage to other components.
