Description
4247 701 8900 – STIHL Grommet Genuine OEM Part for SG 20 Pump
The STIHL Grommet 4247 701 8900 is a genuine OEM rubber mounting and sealing component designed for the SG 20 sprayer pump assembly. This grommet provides cushioning, sealing, and secure positioning for pump-related components, helping maintain proper alignment and leak-free operation.
Grommets play an important role in absorbing vibration and protecting connections from wear caused by movement and pressure cycles. Over time, rubber grommets may crack, harden, deform, or deteriorate due to chemical exposure and repeated use. A damaged grommet can result in leaks, instability, or reduced pump efficiency.
Replacing the grommet with the correct genuine STIHL OEM part restores proper sealing integrity, vibration control, and reliable pump performance.
Manufactured to STIHL factory specifications, this OEM grommet ensures precise fitment, durability, and long-term reliability under demanding agricultural and landscaping conditions.
