Description
Overview:
This grease seal is a genuine Stihl OEM part designed to maintain lubrication and protect the gearbox on Stihl hedge trimmers. Manufactured from durable, oil- and grease-resistant elastomer in a compact circular form, it keeps grease where it should be and helps stop dust, dirt, and moisture entering the drive unit. By preventing leakage and contamination, it supports smooth running and consistent cutting performance while reducing wear on gears and bearings. Precisely matched to Stihl specifications for fit and material quality, it is suitable for routine servicing or repairs on popular models such as the HS81R and HS81RC. Use it to restore reliable sealing in professional and domestic hedge trimming applications where uptime and clean operation matter.
Key Features:
- Genuine Stihl part for assured compatibility and performance
- Helps retain gearbox grease and keeps contaminants out
- Supports smooth blade drive and reduces premature wear
- Robust elastomer construction for resistance to oils and heat
- Accurate fit minimises installation time during servicing
- Contributes to quieter, more efficient operation of the drive system
- Suitable for selected petrol and battery trimmers in the HS/HSA ranges
- Meets OEM standards to match original sealing performance
- Reliable replacement for worn, hardened, or leaking seals
- Helps prevent downtime by maintaining proper lubrication
Typical Applications:
Replacement during routine maintenance, gearbox rebuilds, or when grease seepage is observed around the gear housing. Common in landscaping, grounds maintenance, and estate care where hedge trimmers work for extended periods. Fit this seal to restore proper lubrication control and protection after blade drive servicing or when contamination has compromised the original seal.
