Lip Seal VMQ

Lip seals are usually made of elastic materials such as rubber or polyurethane.
They are shaped like a lip and are usually cut from a round material that is then stretched and installed in a sealing device.

In hydraulic and pneumatic transmission systems, the working principle of lip seals is to rely on the interference between the seal lip and the mating surface and the pressure of the working medium to cause spring deformation of the seal to block the relative movement between the two parts. gap to achieve the purpose of sealing.

Lip seals are usually one-way seals, meaning they only prevent fluid from leaking out in one direction.

Lip seal is a common sealing device mainly used to prevent fluid or gas leakage and maintain the normal operation of the system.

When selecting a lip seal, you need to consider the working conditions and requirements of the system and select the appropriate material and design.

Lip seals are usually made of a variety of rubber materials, including nitrile rubber (NBR), fluoroelastomer (FKM), silicone rubber (VMQ), etc. These materials are used in a wide variety of sealing applications due to their excellent resistance to wear, chemicals, oils and high temperatures.
