Shop Cartridge Cavity Plugs

A Hydraulic Directional Control Valve Cartridge Cavity Plug is a crucial component for maintaining the integrity of a hydraulic system when removing a cartridge valve. These plugs seal off the cavity left by the removed valve, preventing leaks and ensuring the system remains operational. They are ideal for tasks such as flushing after repairs, replacing components, or altering circuit functionality.


Available in various sizes and thread types, including 3/4-16 UNF, 7/8-14 UNF, and M20x1.5, these plugs feature axial bores for optional radial port connections. They match the sealing standards of the valves they replace and are zinc-coated to provide 240 hours of protection against corrosion, as per ISO 9227.
