3. PTFE Molded Gaskets PTFE, or polytetrafluoroethylene, is a highly durable and chemical-resistant material that is commonly used in high-temperature and high-pressure applications.

 

  • c. Silicone Rubber (SI) – these compounds operate effectively in a broad temperature range of -58⁰ F to 356⁰ F (-50 to 180⁰ C). Silicone rubber is a leading choice for its resistance to both low temperatures and heat. The high lubricant absorbency of the material minimizes friction and wear. These oil seals are usually used as crankshaft seals. Silicone has poor resistance to hydrolysis and should not be used in oxidized or hypoid oils.

    In recent years, advancements in spark plug technology have brought about significant improvements. Platinum, iridium, and even diamond-coated spark plugs have been developed, offering longer lifespan, better fuel economy, and increased durability. These premium spark plugs are designed to withstand higher temperatures and pressures, making them ideal for modern high-performance engines. Motor oil seals are typically made from rubber or a similar material that is able to withstand the high temperatures and pressures present in an engine. They are placed in specific locations around the engine to prevent oil from seeping out through gaps or openings. Without these seals, oil could leak out onto the engine parts, causing damage and potentially leading to a loss of lubrication for the engine. The inclusion of 7% steel, often in the form of a metallic insert or spring, further fortifies the oil seal's performance Compatibility with fluids
