- The 20mm thickness provides an excellent balance for many applications; it is thick enough to withstand moderate pressures without being so bulky that it interferes with the assembly of parts. In automotive applications, these gaskets may be found between engine components, ensuring oils and coolants remain where they should, protecting against leakage and subsequent damage.
- In the intricate world of automotive engineering, where every component plays a pivotal role in the seamless operation of vehicles, the unassuming 7mm spark plug wire stands out as a testament to innovation and reliability. This essential conduit for electrical current might be small in size, but its impact on an engine's performance is anything but minor.

The sealing element makes up the interior of the oil seal, and the materials commonly used are:
Nitrile Oil Seals - Nitrile oil seals, which is the commonly used term for acrylonitrile-butadiene rubber seals, is a very good general-purpose option due to the flexibility of use across a variety of components. The resistance is strong against fats, hot water, gasoline, mineral oils, grease and animal oils, making them the most often-used oil seals. They do not have a wide temperature range, making them a poor choice for machinery that can see extreme changes in temperature.

Leather Oil Seals - Leather Seals, also known as Type L Oil Seals, are most common in components that are subject to dirt and poor lubrication. Since they come pre-lubricated and are able to absorb fluids, leather oil seals are able to provide sealing properties in conditions that synthetic rubber is unable to.
