FKM TC oil seal has good high temperature resistance and medium resistance, even at high temperature, it can still maintain good medium resistance and compression deformation resistance.
The representative form of oil seal is TC oil seal, which is a kind of double lip oil seal with self tightening spring completely covered by rubber. Generally speaking, oil seal often refers to this kind of TC framework oil seal. Oil seal is a widely used sealing material component. It is an integral part of any rotating and moving assembly. It encloses the space between the static and moving parts in mechanical equipment. Widely used in various industrial machinery, vehicles, mining, metallurgy, electronics and other industries. It has excellent properties of oil resistance, water resistance, wear resistance, acid and alkali resistance, high temperature resistance and so on.

Acrylonitrile Butadiene Rubber (NBR), usually shortened to Nitrile, was developed in 1941 as the first oil resistant rubber. Grades with high acrylonitrile content have better oil resistance whereas low acrylonitrile content gives better low temperature flexibility and resilience.
Since its establishment in 2008, Hebei Michu Technology Co.,Ltd. has accumulated many
years of technical experience, and can customize various O-ring varieties and specifications according to the needs of customers.
In 2014, we have successfully developed from a factory to a supplier integrating production and trade.
Our company is specialized in producing all kinds of rubber seals, such as O-ring, FKM oil seal, stainless steel PTFE oil seal,
rotary seal (hub oil seal, box oil seal), etc., which are mainly used in hydraulic and pneumatic aspects, and widely used in
plumbing, hardware, home appliances, medical equipment, machinery, electronics, semiconductor, aerospace and other fields The main
materials used in our rubber sealing products are NBR, EPDM, FKM, HNBR, silicon, ACM, ffkm, etc.
Now our company has advanced and perfect production line, which can provide all kinds of rubber seal products with higher cost
performance for our cooperative users, and our company always insists on treating customers with high-quality products and
professional services, which has won good comments and trust from customers all over the world
