Key Features
- Genuine OEM Sealing Integrity — sourced directly from Honda, this washer provides the precise seating surface the relief valve depends on to regulate pressure correctly within the hydraulic system.
- Direct OEM Replacement — matches the original part for fitment on H3011 and H3013 riding mowers and H4514 and H4518 lawn tractors; installs without rework or modification.
- Serial Number Verification Recommended — Honda updates components at production breakpoints, so check your unit's serial number against the fitment table to confirm part number 25433-VD6-000 is correct for your machine.
The relief valve washer serves as a seating and sealing element within the hydraulic relief valve assembly on Honda riding mowers and lawn tractors. The relief valve itself limits hydraulic pressure in the system, protecting the pump and drive components from overload — and this washer ensures the valve seats and seals correctly so it can open and close at the right pressure. When the washer is worn, damaged, or missing, the valve may not seal properly, leading to pressure loss, erratic drive response, or accelerated wear on other hydraulic components.
