A heating coil typically consists of a wire or metal strip wound into a coil shape. The most common materials used for these coils are nickel-chrome alloys, Kanthal (iron-chromium-aluminium alloy), or copper, each chosen for their excellent conductive and resistance properties. The design of the coil, including its diameter, length, and number of turns, affects its heating efficiency and the specific temperature it can achieve.

  • The rubber component, typically made from high-quality elastomers, provides the seal with the necessary elasticity to adapt to different temperatures and maintain a tight fit within the mechanical assembly. It ensures a reliable barrier against oil leakage, preventing contamination and maintaining the integrity of the lubrication system.
  • One of the key functions of a mechanical oil seal is to prevent the leakage of oil or grease from the rotating shaft of a machine. This is achieved through the use of a flexible sealing lip that makes contact with the shaft and effectively seals the gap between the shaft and the housing. The seal is typically made from a durable elastomeric material such as rubber or polyurethane, which is resistant to abrasion and can withstand high temperatures and pressures.

  • Oil seals, also known as rotary shaft seals or lip seals, are a specific type of gasket designed to prevent the leakage of oil or other fluids in rotating shafts. 

  • Oil seals operate by creating a tight barrier between two moving or stationary parts, such as a shaft and housing, to prevent oil from escaping and contaminants from entering the system. This is essential for maintaining the efficiency and performance of the machinery, as well as preventing potential safety hazards.


  • In the intricate machinery of an automobile engine, every component plays a crucial role, and the 4.6 valve cover gasket is no exception. This seemingly small part is a vital element in ensuring the optimal performance and longevity of the engine.

  • Rubber oil seals are widely used in various applications due to their versatility, durability, and resistance to oil and other fluids. These seals are designed to provide effective sealing solutions for rotating or reciprocating shafts, preventing the escape of lubricants and the entry of contaminants. Rubber oil seals play a crucial role in maintaining the efficiency and longevity of industrial machinery, automotive engines, and other equipment by ensuring proper lubrication and protection of internal components.

  • The Importance of Metallic Oil Seals in Industrial Applications

  • As the pressure increases, the radial load and the friction of the sealing lip increase in contact with the shaft. As with temperature, each oil seal has a recommended pressure for optimum performance. Excessive pressure causes the seals to wear more quickly and consequently have a shorter life.
