- Petroleum oil and sour gas resistant
- To address the high cost of spark plugs and wires, several solutions can be considered. First, manufacturers can seek to reduce the cost of raw materials by sourcing from lower-cost suppliers or using more cost-effective materials. Second, they can optimize the manufacturing process to reduce labor costs and other indirect costs. Third, they can engage in cost-sharing arrangements with suppliers and distributors to reduce the overall cost of the products.
- Self-contained
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.
- Its ubiquity notwithstanding, the small rubber gasket's significance is often overlooked until a failure occurs

When installing a 38x52x7 oil seal, it is important to ensure that the seal is properly lubricated and aligned with the shaft. This will help to minimize friction and wear, and extend the life of the seal. It is also important to regularly inspect the seal for any signs of damage or wear, and replace it if necessary to prevent oil leakage.

Coat the sump flange with gasket-sealant and fit the flat parts of the gasket to it, ensuring that they are exactly positioned and joined.
