An Engine Oil Drain Plug Seal O Ring is used to fit snugly around the plug and create a seal between the plug and the engine oil pan. The circular cross-sectional design of the O Ring allows it to be compressed and deformed when inserted into a groove of the plug. This deformation generates a tight and effective seal that prevents the unwanted escape of oil or the ingress of contaminants.Attributes:• Endures the harsh operating conditions within the engine and provides a reliable sealing• Has low friction properties, reducing wear and tear on mating surfacesApplications:An Engine Oil Drain Plug Seal O Ring prevents oil from leaking out of the engine oil pan and maintains the correct oil levels for lubricating the engine components.
