- The cost of installation should also be considered
- Another popular type of oil seal is the mechanical seal, which consists of two sliding surfaces that are pressed together to form a seal. Mechanical seals are known for their durability and reliability, making them ideal for high-pressure and high-speed applications. These seals are commonly used in pumps, compressors, and fluid handling equipment.
- 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.
- The design and material composition of an oil seal are crucial factors in determining its performance and durability. The seal must be designed to withstand the high pressures and temperatures that can occur within the machine, as well as the abrasive and corrosive substances that may come into contact with it. Common materials used in oil seals include rubber,PTFE, and synthetic materials, each with its own unique properties and applications.
- In addition to helping ignite the fuel in certain conditions, the spark plug also plays a role in maintaining the proper temperature of the combustion chamber
A: with minor lip
Shaft Hardness
3. TEMPERATURE: Similar to the pressure level, you need to know what temperature your machinery can operate at. You need to choose a seal that can withstand the heat or cold. PTFE have the widest rang of temperature, making them a safe option when you are uncertain of the range.
The range of uses of peroxydically cross-linked EPDM includes in hot water and steam seals. EPDM is also very resistant to ageing and ozone. Compared with the usual types of synthesis natural rubber it has good resistance to cold temperatures. EPDM is not resistant to aliphatic or aromatic hydrocarbons or mineral oil products. Resistance to chemicals, and also to oxidising agents, is very good. Temperature range from -50 °C to +140 °C depending on type.


First, an elastomer, most often nitrile, is vulcanised to a metal ring. This creates a stiffening effect that includes a specialised metal tension spring directly behind the sealing lip, keeping the oil seal firmly in place against the moving part.
Overall, neoprene foam gaskets are a reliable and cost-effective solution for sealing and insulation applications in a wide range of industries. Their resilience, sealing properties, insulation capabilities, and versatility make them a preferred choice for manufacturers, engineers, and maintenance professionals who depend on high-quality gaskets to ensure the performance and longevity of their equipment.
