  • In the realm of aviation, the jet engine is the heart that powers aircraft, propelling them through the skies with remarkable speed and efficiency. Within this sophisticated machine, spark plugs play a vital role, serving as the ignition source that ignites the combustion process, which in turn generates the immense power required for takeoff and sustained flight.
  • Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.

  • Silicone Rubber (SI): A popular choice for its resistance to low and high temperatures (-58 to 356°F, or -50 to 180°C). Silicone rubber has high lubricant absorbency, which reduces friction and wear, making it ideal for crankshaft seals. However, it is unsuitable for oxidized or hypnoid oils due to its poor resistance to hydrolysis.

  • Routine maintenance of your engine, including checking and replacing valve cover gaskets when needed, is essential to keeping your engine running smoothly and efficiently. By using high-quality gaskets, such as the 305 valve cover gaskets, you can prevent oil leaks and ensure that your engine is performing at its best.
