  • PTFE Oil Seals - A relatively new and exciting oil seal, the use of polytetrafluoroethylene means that they can withstand dry or unlubricated operations. With a massive thermal range of  -130ºC to +200ºC and a strong resistance to chemicals, they are considered to be the future of rotary shaft seals.

  • Moreover, these seals also protect against contamination by dust, dirt, and other debris. This is especially important in environments where cleanliness is paramount, like in food processing or pharmaceutical industries, where even minute particles can compromise product quality.
  • When selecting spark plugs for motor vehicles, it is important to consider the specific requirements of the vehicle, including heat range, electrode design, and material composition. Iridium spark plugs are known for their fine-wire electrode and superior durability, making them suitable for a wide range of motor vehicle applications. The use of high-quality iridium spark plugs can contribute to optimized engine performance, fuel efficiency, and emissions control, ensuring reliable operation and reduced environmental impact.

    Names and functions of seal components 

  • Peroxide
  • Firstly, it is essential to understand what sets iridium spark plugs apart from their counterparts. Iridium, a precious metal, is utilized in the electrode of these plugs due to its high melting point and superior electrical conductivity. This results in a longer service life and better performance under extreme conditions compared to conventional copper or platinum plugs. The enhanced durability means fewer replacements over time, which can be a compelling argument for the higher initial cost.
  • In the automotive industry, these gaskets are used extensively in engine components, such as the cylinder head gasket which separates the combustion chambers from the cooling system, preventing oil and coolant mixing. A faulty gasket here can result in engine overheating or failure, underscoring the importance of quality in their manufacture.
  • Low wear and tear
  • In conclusion, the cylinder head gasket is a vital component of your engine's performance. By identifying and replacing a failed gasket, you can prevent costly repairs and ensure that your engine runs smoothly for years to come.

  • To replace the front valve cover gasket, the engine must be cool and the area around the valve cover must be clean. The valve cover is typically held in place by a series of bolts or screws that must be removed to access the old gasket

  • The plug aspect of the shorty spark plug is where the magic happens—the part that fits into the engine, sealing the combustion chamber while facilitating the flow of electricity
  • Hardening or Cracking: Exposing oil seals to high temperatures for extended periods may cause the sealing material to harden or crack. This breakdown compromises the seal’s effectiveness and can lead to leakage.
  • Spark plugs also undergo immense stress due to high temperatures and pressures within the engine
  • Because of the higher temperature resistance of FKM, this material is also chosen for applications where higher speeds play a role, which raise the temperature at the sealing lip considerably. Usually, using FKM will result in a longer life than using NBR. This compensates the higher price of FKM compared to NBR, as an FKM does not have to be replaced as frequently. The low temperature resistance of standard FKM is limited to -15 ˚C.

  • The material of the sealing lip is chosen according to the liquid to be sealed and the rotational speed. For larger shafts, an NBR sealing lip can cope with surface speeds of up to 10-12 m/s, while an FKM lip is suitable for speeds of up to 35-38 m/s. 

  • Application Requirements: The specific requirements of your application are critical to making the right choice. For example, if the seal is for a food processing machine, it must meet FDA standards.
