A Hydraulic Plug Gasket is a thin, ring-shaped component made from annealed copper. It sits between the hydraulic plug and the threaded port it screws into. The hydraulic plug copper gasket is used to provide an effective seal between hydraulic plugs and the ports they are inserted into. It features a center bore that fits the shape of the mating components.Attributes:• Resists corrosion from hydraulic fluids and external elements• Manufactured to precise specifications and is built for durability and reliabilityApplications:A Hydraulic Plug Gasket is compressed between the flat surface of the plug and the threaded surface of the port. This compression creates a tight seal that prevents hydraulic fluid from leaking out around the threads.
