Trimmer O-Ring 35499

This rubber O-ring is a genuine OEM part that is designed for use with various outdoor power equipment models and is sold individually. O-rings are used to seal connections between parts and because of the nature of this O-ring contacting gas and oil, over time it will become brittle and less effective, or crack. When this happens, you will need to replace the part, and this one is a guaranteed fit. This O-ring is typically attached to an oil fill tube for measuring the level of oil in your equipment, to help create the necessary seal that prevents the cap from becoming loose and dirt from entering the tube.
