- When choosing a spark plug for your vehicle, it is important to consider factors such as the type of engine, driving conditions, and manufacturer recommendations. The 794 00055A spark plug is a versatile option that is suitable for a wide range of vehicles and driving conditions. Its high-quality construction and reliable performance make it an excellent choice for replacing worn or damaged spark plugs.
- The manufacturing process involves several steps, including molding, shaping, coating, and testing. The electrodes are shaped and calibrated to exact measurements, while the insulator is coated with a ceramic material to provide insulation and durability. The housing is also carefully crafted to withstand the high temperatures and pressures within the engine cylinder.

Another important factor to consider when choosing spark plugs for your MK7 GTI is the electrode material. The electrode material can vary between spark plugs and can have an impact on the performance of your engine. Copper, platinum, and iridium are common electrode materials used in spark plugs. Iridium spark plugs are often preferred for performance cars like the MK7 GTI due to their durability and ability to maintain a stable spark.
Seals are designed to create a tight seal around the shaft by utilising a combination of lip geometry, surface tension, and lubrication. When the shaft rotates, the lip of the oil seal comes into contact with the shaft surface, creating a frictional force that generates heat. This heat helps to soften and conform the elastomeric material of the oil seal to the shape of the shaft, ensuring an effective sealing action.
The oil seal should be tough enough to withstand the pressure and the vibrations caused by the shaft and bore. Check if the oil seal is strong enough to tolerate the pressure and vibration.

When selecting car engine head gaskets and automotive rubber gaskets, it is crucial to prioritize quality, durability, and compatibility with specific vehicle models. High-quality gaskets are designed to withstand the demanding conditions of automotive operation, providing reliable sealing solutions that contribute to the overall performance and safety of the vehicle. Choosing reputable suppliers and manufacturers known for producing high-quality gaskets is essential to ensure the reliability and longevity of these critical components.
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.
