This is almost similar to that of ‘A’ type seal. But this has the metal case placed outside. When the housing is rough, temperature is high and working conditions are severe, this type is preferred

Industrial Oil Seals: Applications and Importance

Note how the mounting nuts or bolts are fitted, then undo them. Have ready some wooden wedges to use as supports, and a strong helper to hold the engine steady.

Spark plugs and wires are essential components in the ignition system of internal combustion engines. Spark plugs play a critical role in igniting the air-fuel mixture within the engine cylinders, initiating the combustion process that powers the vehicle. High-quality spark plugs and wires are crucial for ensuring efficient fuel combustion, optimal engine performance, and reduced emissions. As a result, the quality and reliability of spark plugs and wires directly impact the overall efficiency and environmental impact of the vehicle.

If you are installing an o-ring to serve as a backup, make sure you put it on the low-pressure side of the system. This will make the high-pressure side push the o-ring against the backup.

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.

Temperature - Just like pressure, the temperature that your oil seal will be operating in must be known so that you can choose one that can withstand the heat or cold. PTFE have the widest range of temperature, making them useful for machines who can see usage in extreme weather or elements.
