  • The material composition of an oil seal is also essential. Typically, Oil Seal 20x35x7 is made from a combination of rubber (such as NBR, HNBR, or FKM) for flexibility and resilience, and a metal insert for strength and durability. The rubber compound allows the seal to adapt to different temperatures and chemical environments, while the metal reinforcement provides resistance against pressure and wear.
  • Viton Oil Seals - A synthetic rubber and fluoropolymer elastomer, Viton is used to make oil seals that provide resistance in both high temperature, up to 250°C and low compression set components. They also offer a high resistance to chemicals and abrasions, so they can be used in elements that regularly interact with petroleum and solvents.

  • Radial oil seals are a critical component in the operation of rotating machinery. These seals are designed to prevent the leakage of oil from the housing of the machine while allowing the shaft to rotate freely. They are widely used in a variety of applications, including automotive engines, pumps, turbines, and compressors.
  • These oil seals are the best for applications involving high temperatures. It’s suitable for temperatures between -4 degrees Fahrenheit and 392 degrees Fahrenheit. Also, it’s highly resistant to acids, dissolvent materials, and other chemicals. Viton (FKM/FPM) oil seals can run at a maximum speed of 38 m/s.

  • Despite these benefits, die-cut silicone gaskets are relatively lightweight and easy to install, reducing production downtime and simplifying maintenance processes. Their versatility allows them to be customized in terms of thickness, hardness, color, and shape, making them adaptable to a wide range of applications.
  • An aircraft spark plug is a crucial component in the ignition system of an aircraft engine. It plays a vital role in generating the spark that ignites the fuel-air mixture in the engine's combustion chamber, creating the power needed to propel the aircraft forward.
  • The use of SC oil seals also plays a vital role in environmental conservation efforts. By preventing oil leaks, these seals help in reducing waste and potential pollution. When lubricants do not escape from their intended environments, there is less likelihood of them entering ecosystems, where they can cause harm to wildlife and disrupt ecological balances.

  • A valve cover gasket, as the name suggests, is a seal that sits between the engine's valve cover and the cylinder head. Its primary purpose is to prevent oil leaks from the engine's lubrication system, safeguarding vital components from contamination and potential damage. It also helps maintain the necessary pressure within the engine, contributing to efficient fuel combustion.

  • The CR6HSAA spark plug is a product of advanced engineering, designed to cater to high-performance engines, particularly those in automotive, marine, and small engine applications. The 'CR' in its name signifies that it is a copper core spark plug, known for its excellent heat dissipation properties. Copper, being an excellent conductor of electricity, ensures a faster and more consistent spark, contributing to improved ignition efficiency.
  • The benefits of using Double Platinum Spark Plugs are manifolddouble platinum spark plugs. They not only improve engine performance but also reduce harmful emissions. The improved combustion process results in cleaner exhaust gases, making these spark plugs an environmentally friendly choice. Additionally, their durability means less frequent replacements, saving vehicle owners both time and money.

  • The 35% refers to the ideal contact ratio between the oil seal lip and the rotating shaft. This percentage is crucial as it ensures a balance between sealing effectiveness and minimal friction. If the contact ratio is too high, excessive heat generation and wear can occur, potentially leading to seal failure. On the other hand, a low contact ratio may result in inadequate sealing, allowing oil to escape or debris to enter.
