O type rubber ring is suitable for hydraulic oil, hydraulic oil, hydraulic oil, two ester series oil, gasoline, water, silicone grease, silicone oil and other media. Is the most widely used, the lowest cost of rubber seals. Not applicable to polar solvents, such as ketones, nitro hydrocarbons, ozone, MEK and chloroform. General temperature range is -40~200. HNBR hydrogenated nitrile rubber O ring with corrosion resistance, tear resistance and compression deformation, ozone resistance, weather resistance, good resistance to sunlight.

O type rubber sealing ring is widely used in locomotives, cars, tractors, engineering machinery, machine tools and various hydraulic pneumatic components such as sealing, sealing and fixing, can undertake reciprocating and rotary motion, in mechanical product seal O type rubber sealing occupy more than 50%. According to the need, can be used for the production of high temperature, low temperature vacuum, high pressure and not the same as the medium of all kinds of special O type rubber sealing ring, sealing ring and special rubber sealing products. Compared with other types of sealing ring, O type sealing ring has the following advantages:

1, suitable for a variety of sealing forms: static sealing, dynamic sealing

2, suitable for all kinds of materials, sizes and grooves have been standardized, strong interchange

3, suitable for a variety of sports: rotary motion, axial reciprocating movement or combination of motion (such as the rotation of the reciprocating combination)

4, suitable for a variety of different sealing medium: oil, water, gas, chemical medium or other mixed media

Through the selection of appropriate rubber materials and appropriate formula design, to achieve the oil, water, air, gas and a variety of chemical medium effective sealing effect. Wide temperature range (- 60 C + 220 C), the use of a fixed time pressure up to 1500Kg/cm2 (with the reinforcement ring and). O design is simple, compact structure, convenient assembly and disassembly, the section structure is extremely simple, and has a sealing effect, sealing performance is reliable, so it is very easy to install and replace.
