Rubber type
O.D. (outside diameter) surface The O.D. surface affixes the oil seal to the housing and prevents leakage , through the fitting area, of substances to be sealed, while excluding contaminants.
For instance, platinum and iridium-tipped spark plugs offer longer life and better performance due to their superior resistance to wear For instance, platinum and iridium-tipped spark plugs offer longer life and better performance due to their superior resistance to wearspark plug motor. Some modern engines even use multiple spark plugs per cylinder for enhanced ignition.The cover is fixed by nuts or bolts on top, or by screws round the edge. Loosen them all and remove them with their washers. If there are several oil-sealing washers under each fixing, note their order.
They are typically made from elastomers such as rubber or silicone and consist of an outer metal case with a sealing lip on the inner side.

In this an auxiliary lip is provided along with the regular sealing lip. The additional dust lip protects the main sealing lip against dust and other fine solid contaminants and therefore this type is recommended for use in polluted environments. To achieve a long lifetime a suitable lubricant between the two sealing lips should be applied.
