1. O type sealing ring series
It has fluorine rubber, nitrile rubber, silica gel, ethylene propylene rubber, double fluorine rubber and other materials. It is widely used in various machinery and is resistant to various petroleum-based oils and various chemical media: the use of non-rubber can meet- Temperature range of 60°C-+200°C (double fluorine rubber FFKM can reach more than 300 degrees through a specific curing method), the use pressure range: <10MPa (hydraulic), <1MPa (pneumatic) <16MPa (static sealing) nitrile The expansion rate of rubber and gasoline resistant (90,93,97) is 0.

2. Y-type sealing ring
Products made of fluorine rubber, nitrile rubber, chloro rubber and other materials are widely used in hydraulic, mechanical, pneumatic and other industries. The resistant petroleum base oil has excellent abrasion resistance, and the selection of different types of rubber can meet the temperature range of -60℃-+200℃.

3. V-shaped sealing ring
It is an axially acting elastic rubber sealing ring, used as a pressureless seal of the rotating shaft. The sealing lip has good mobility and adaptability, can compensate for larger tolerances and angle deviations, can prevent internal grease or oil from leaking outward, and can also prevent external splashing or dust from intruding.
