Selecting Quality Gaskets
The depth of the bonded seal can be less and the space between the bore and the outside diameter can be changed for ease of fitting. The bonding of rubber to metal is an important factor to be considered in the manufacture of such seals and should be considered carefully, since failure of the bond will cause the seal to fail. The metal case of the oil seal is usually made from mild steel of deep drawing quality which enables blanking, punching, stamping of the steel to the required dimensions.

794 00055a spark plug. Over time, spark plugs can become fouled with carbon deposits, which can decrease their effectiveness. The 794 00055A spark plug is designed to resist fouling, ensuring that it will continue to provide a consistent spark for optimal engine performance.


By preventing lubricants from escaping, they protect key components of machinery from being damaged by leaks of various fluids. Everything from car engines to assembly machines use these oil seals to remain free from any harmful interactions that can cause serious and expensive damage to any of their critical parts.

Material selection is important to the life of a radial shaft seal. The elastomer’s resistance to temperature, abrasion, chemicals, weather, sunlight, and ozone can affect a profile’s longevity and performance. The two most prevalent materials are Nitrile and Viton. See our Oil Seal Materials page for details on compounds and chemical compatibility.
advantage:
ERIKS type R (type A according to the DIN standard) is identical in shape to type M, but has a rubber outer case with metal reinforcement on the inside. The rubber creates a good seal in the housing, even if the housing has suffered minor damage or is not in its best condition for other reasons. The RST version has a dust lip. These types are often chosen to replace a type with a metal outer case because they are easier to install and can cope with minor damage to the groove, such as scratches.
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.
