- In addition to igniting the fuel-air mixture, the spark plug also plays a crucial role in ensuring optimal engine performance. A properly functioning spark plug can improve fuel efficiency, reduce emissions, and increase engine power
jet engine spark plug. On the other hand, a faulty spark plug can lead to misfires, reduced engine performance, and even engine damage. - Proper installation and maintenance of oil seals are also crucial to their effectiveness. A poorly installed oil seal can lead to oil leakage and machinery failure, while regular maintenance can help to prolong the life of the seal and prevent costly repairs. It is important to follow the manufacturer's guidelines for installation and maintenance to ensure that your oil seals perform at their best.

twin spark plug. This is especially noticeable during high-speed driving or when accelerating from a standstill, where every ounce of power is crucial for optimal performance.
PTFE, which is used in the well-known brand Teflon®, is less commonly used, but it is the preferred material for specific rotating seals in the chemical, food and pharmaceutical industries. This material is notable for having a very low frictional resistance and the best chemical resistance. It can also withstand a very wide range of temperatures in these types of seals; -80 ˚C to 200 ˚C. The shafts on which oil seals with PTFE lips are used require a harder and finer finish. Something like an axle sleeve can also be used to meet this requirement.
Common lip materials available for use in our oil seals include:
Shaft oil seals are an essential component in machinery and equipment used in various industries. They play a crucial role in preventing the leakage of fluids and keeping contaminants out of the system, ensuring smooth operation and prolonging the lifespan of the machinery.

They are generally utilised for the following purposes:

The shaft on which the oil seal is mounted has to be ground to a rough surface finish. The shaft also should be hardened to prevent grooves forming on the shaft when the pressure is exerted by the spring on the seal. The area where the seal is fitted also has to be ground to prevent grooves that tend to wear out the lip of the oil seal faster than normal.
Car iridium spark plugs are a popular choice for modern vehicles due to their durability, high melting point, and superior conductivity. Iridium spark plugs offer enhanced performance and longevity compared to traditional copper or platinum plugs. The use of iridium in the electrode design allows for a smaller center electrode, promoting more efficient combustion and improved engine performance. Car iridium spark plugs are known for their ability to maintain optimal engine performance over an extended service life.
