Description
Overview:
The Valve Seat Insert 4736 512 1500 is a genuine Stihl component for maintaining the sealing performance of pressure washer pumps, including the RE521 and RE551. This precision‐machined brass insert provides a hard, accurate seating surface for the valve, helping to prevent bypass and leakage so the pump can build and hold pressure efficiently. Designed to OEM tolerances for Stihl RE‐series machines, it supports reliable operation under frequent start-stop use and exposure to water and detergents. Fitting a new seat insert restores proper valve function when the original surface is worn, pitted, or damaged, improving performance and protecting other pump parts from undue wear. A straightforward like‐for‐like replacement, it is a practical service part for workshops, contractors, and home users.
Key Features:
- Genuine Stihl part for assured compatibility and performance
- Precision-machined brass for durability and corrosion resistance in wet, detergent‐rich environments
- Restores a tight seal at the valve, reducing leaks and pressure loss
- Helps maintain correct pump output and efficiency over time
- Made to OEM dimensions for a direct replacement with reliable fit
- Supports longer service life of valves and pump components by preventing blow‐by
- Suitable for routine maintenance or refurbishment to reduce downtime
- Compact, robust insert designed for heavy, regular use in professional and domestic settings
Typical Applications:
Used when servicing Stihl RE‐series pressure washer pumps to correct pressure loss, erratic performance, or evidence of valve seat wear. Ideal for preventative maintenance in workshops, on building sites, facilities management, agriculture, vehicle wash bays, and at home for cleaning drives, patios, machinery, and tools.
