Seal-O-Ring 237-81

This individual rubber O-ring is a genuine OEM part for various outdoor equipment models and has an approximately 1-inch inner-diameter. O-rings are typically used to seal various gaps within hydraulic systems to prevent the escape of liquids or gases, and if you notice that the motor of your equipment is leaking or performing poorly, it may be a sign of an aging O-ring, because over time they lose their elasticity and crack. Be sure to check any diagram of your equipment for the exact placement of this O-ring.
