Description
Overview:
The Annular Buffer/Rubber Mount is a genuine Stihl spare for large-frame chainsaws such as the MS640 and 066. Made from tough black elastomer rubber with a bonded metal sleeve, this annular bush forms part of the anti‐vibration system, isolating engine movement from the handles and body.
