Description
Overview:
This Valve Body is a genuine Stihl OEM component for backpack sprayers, engineered to restore and maintain reliable fluid control. Built from a hard‐wearing, chemical‐resistant polymer, it forms part of the sprayer's internal flow path and check system, helping to hold pressure, prevent backflow, and keep the spray pattern consistent. It is designed specifically for Stihl SG 51 and SG 71 sprayers and replaces worn, cracked, or leaking valve bodies without modification. Identified by MPN 4255 512 0700, it is manufactured to Stihl specifications for proper fit and function. Use it during routine servicing or when symptoms such as loss of pressure, drips, or poor priming appear, to keep your sprayer working efficiently and minimise downtime. This is a Genuine Part.
Key Features:
- Genuine Stihl OEM part for exact fit and reliable operation on SG 51 and SG 71
- Precision-moulded polymer resists typical garden and grounds-care chemicals
- Restores correct check action for better priming and stable operating pressure

Typical Applications:
