Description
Overview:
The Oil Seal 14x20x3.5 is a genuine Stihl OEM component designed to stop oil escaping around rotating shafts in your machine. Made from hard‐wearing sealing elastomer and engineered to original specifications, it helps keep the lubricants where they should be and contaminants out. This supports smooth running and protects internal parts from premature wear. With precise dimensions of 14 x 20 x 3.5 mm (0.55 x 0.79 x 0.14 inches), it is built to fit correctly in the designated housing without modification. Ideal for Stihl professional equipment such as the 050 and 051, it is also widely used across selected older chainsaws and cut-off saws where this size is specified. MPN: 9642 003 1440.
