The rubber O-ring is suitable for use in petroleum-based hydraulic oil, glycol-based hydraulic oil, diester-based lubricating oil, gasoline, water, silicone grease, silicone oil and other media. It is currently the most versatile and lowest cost rubber seal. Not suitable for use in polar solvents such as ketones, ozone, nitrohydrocarbons, MEK and chloroform. The general temperature range is -40~200 °C. HNBR hydrogenated nitrile rubber O-ring: It has excellent corrosion resistance, tear resistance and compression set resistance, and is resistant to ozone, sunlight and weather. Rubber seal O-rings are widely used in diesel locomotives, automobiles, tractors, construction machinery, machine tools and various hydraulic and pneumatic components. They can bear the seals of fixed, reciprocating and rotary motion. O-type rubber seals in the sealing of mechanical goods. More than 50%. According to the needs, it can produce O-type rubber sealing rings, sealing rings and special-shaped rubber sealing products for various special purposes such as high temperature resistance, low temperature vacuum, high pressure and different media. O-rings have the following advantages compared to other types of seals: 1, suitable for a variety of sealing forms: static seal, dynamic seal 2, suitable for a variety of materials, size and groove have been standardized, strong interchangeability 3, suitable for a variety of sports: rotary motion, axial reciprocating motion or combined motion (such as rotary reciprocating combined motion) 4, suitable for a variety of different sealing media: oil, water, gas, chemical media or other mixed media Effective sealing of oil, water, air, gas and various chemical media through the selection of suitable rubber materials and appropriate formulation. The temperature range is wide (-60 °C ~ + 220 °C), and the pressure can be up to 1500Kg/cm2 when used in fixed use (combined with reinforcing ring). The O-ring is simple in design, compact in structure, convenient in assembly and disassembly, its sectional structure is extremely simple, and it has a sealing function and reliable sealing performance, so installation and replacement are very easy.
