  • Wide operational temperature range and good abrasion resistance
  • One of the key advantages of the F7TC Spark Plug is its durability. Traditional spark plugs can wear out quickly due to the high temperatures and vibrations found in modern engines. However, the F7TC Spark Plug is made from a special material that can withstand extreme conditions, ensuring long-lasting performance and reducing the need for frequent replacements.
  • Applications
  • Nitrile Oil Seals – Also known as Acrylonitrile-butadiene rubber seals, is a particularly good general-purpose option due to its flexibility of usage. They are the most often used oil seal due to its strong resistance against hot water, fats and animal oils, gasoline, mineral oils, and grease. They cannot however survive extreme temperatures.
  • Fluid side face The front-end face of the seal is called the nose. The nose is made of rubber and forms a gasket seal when compressed on the housing shoulder.

  • Common causes of oil seal failure

  • The defect of fluoro rubber is 
  • 140mm rubber gasket. Plumbing Systems 40mm rubber gaskets are commonly used in plumbing systems to provide a watertight seal between pipes, fittings, and valves. Their chemical resistance and temperature resistance make them suitable for use in both hot and cold water systems.
  • Minor lip The minor lip prevents the entry of dust and contaminants from outside.
    Lubricant can be retained in the space between the main lip and the minor lip.

  • Double Springs
  • Regular maintenance is also crucial for the longevity of oil seals. Regular inspection and replacement of worn or damaged seals can prevent costly repairs and downtime. It is also important to ensure that the lubrication system is properly maintained to keep the seal in optimal condition.
  • The lip is specially designed to ensure the oil seal works effectively with the different forces that arise during rotation. Many different designs and materials are used, so countless types of oil seals are available. These are chosen according to the application; pumps, gearboxes, wheels, and many other rotating applications where fluids need to be sealed. They are used in a variety of sectors, such as the chemical industry, manufacturing, wind turbines, automotive sector, food industry, and more. Oil seals are used in nearly all sectors.

  • - Remove the old gasket carefully to avoid any damage to the valve cover or cylinder head.
  • Thoroughly clean the sleeve at the back of the pulley, and look for any roughness on it where it touches the seal. If necessary, smooth it with fine wet-and-dry abrasive paper.
