- Verified Part Number Fitment — order with confidence using Bomag part number 05821043 to confirm you have the correct cap for your machine
A rain proof cap covers exposed openings — such as hydraulic ports, filler necks, or vented connections — to prevent water, mud, and debris from entering critical systems while the machine is in operation or stored outdoors. When this cap is missing, cracked, or improperly seated, moisture can work its way into fittings and cause corrosion, fluid contamination, or accelerated wear on the components it protects. Replacing a worn or lost cap promptly with a genuine Bomag part restores the original level of environmental protection and keeps underlying systems clean and functional.
