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.
Oil seals, also known as rotary shaft seals or lip seals, are a specific type of gasket designed to prevent the leakage of oil or other fluids in rotating shafts.
Different types of rotary shaft seals are available in the market, including radial lip, axial lip, and mechanical face seals.
Proper installation and maintenance of mechanical oil seals are crucial to ensure their effectiveness and longevity. It is important to select the correct seal design and material for the specific application, as well as to install the seal properly to ensure a tight and secure fit. Regular inspection and replacement of oil seals at recommended intervals are also important to prevent leaks and potential damage to the equipment.

Furthermore, iridium spark plugs are designed to withstand high temperatures and extreme conditions inside the engine. This means they are less prone to fouling and misfiring, even under intense driving conditions. This reliability makes iridium spark plugs a great choice for performance cars or vehicles that are used for towing or heavy-duty applications.

The first step in installing oil seals is to clean the surface where they will be placed. Dirt, debris, and other contaminants can cause the oil seal to become damaged or misshapen, leading to leaks. Clean the surface with a solvent or soap and water, and make sure it is completely dry before installing the oil seal.
