- Metal cased
The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.
- In conclusion, the PCV valve cover gasket might be a small piece in the grand scheme of a vehicle's engine, but its impact on overall engine health and environmental sustainability cannot be overstated. By ensuring its proper function and timely replacement, car owners can prolong their engine's lifespan, improve fuel efficiency, and contribute to a cleaner environment. Remember, prevention is always better than cure, and in the case of the PCV valve cover gasket, this rings particularly true.

A patent for an oil seal was filed by Nelson Thomas Edward on August 12, 1937, and published a year later. There were two purposes described. The device was to provide an oil seal between a fixed housing and a rotating part. The seal is described as
- In manufacturing settings, high heat rubber gaskets are used in equipment such as ovens, furnaces, and industrial machinery that operate at high temperatures. These gaskets help to maintain a tight seal between components, preventing heat loss and ensuring the efficiency of the equipment.
A mechanical tool called an oil seal keeps lubricant from leaking out of the machine. It accomplishes its goal by sealing the equipment’s moving and stationary parts. Additionally, it prevents impurities from getting inside the machine and shortens its lifespan, an important role it completes. Numerous oil seals exist, including PTFE lip oil seals, rubber fabric oil seals, and rotating V-seals. An oil seal kit is a set of oil seals with the necessary dimensions and desired characteristics. An oil seal kit is more cost-effective and advantageous than buying individual oil seals.
