- These seals are typically made from a variety of materials, including metals, elastomers, and plastics, depending on the specific requirements of the application. The material selection is critical, as it must withstand the harsh conditions within the machinery, including high temperatures, pressures, and exposure to various chemicals.

ERIKS type GV (type C according to DIN) is equivalent to type M, but is a heavy-duty version with a double metal casing. This can be a useful solution with larger diameters in more demanding applications. There is also a version of this type with a dust lip; the GVST (type CS according to DIN).
Oil Seals 101 – The Ultimate Guide
Also known as a Rotary Shaft Seal, Shaft Seal, Lip Seal, Elastomeric Lip Seal or any variation of these. It is a simple device for excluding dust, dirt, water or any other contaminant whilst retaining lubricant in rotary shaft equipment. Generally, it has been developed as a means of protecting the bearings of rotating shafts.

In addition to the cost of the spark plugs themselves, it is also important to factor in the cost of labor for installation. If you are not comfortable working on your car yourself, you may need to pay a mechanic to install the spark plugs for you. The cost of labor can vary depending on the shop and location, so it is a good idea to get quotes from multiple places before making a decision.
Oil seals, also known as shaft seals, are radial lip type seals which are primarily used for retaining lubricants in equipment having rotating, reciprocating or oscillating shafts. The rotating shaft application is most common.
As the pressure increases, the radial load and the friction of the sealing lip increase in contact with the shaft. As with temperature, each oil seal has a recommended pressure for optimum performance. Excessive pressure causes the seals to wear more quickly and consequently have a shorter life.
