The rubber O-ring developed by Dongguan Rubber Materials Co., Ltd. is suitable for use in petroleum-based hydraulic oils, glycol-based hydraulic oils, diester-based lubricating oils, gasoline, water, silicon greases, and silicone oils. It is the most widely used and lowest cost rubber seal. Not suitable for use in polar solvents such as ketones, ozone, nitrohydrocarbons, MEK, and chloroform. The general use temperature range is -40~200°C. HNBR Hydrogenated Nitrile O-rings: Excellent resistance to corrosion, tear and compression, ozone resistance, sunlight resistance, and weather resistance.
Rubber seal O-rings developed by Dongguan Rubber Materials are widely used in the sealing of diesel locomotives, automobiles, tractors, construction machinery, machine tools, and various hydraulic and pneumatic components. They can perform fixed, reciprocating, and rotary motion seals in the sealing of mechanical goods. O-type rubber seals account for more than 50%. According to needs, it can be used for various special purpose O-type rubber seals, seals and special-shaped rubber sealing products for high temperature, low temperature vacuum, high pressure and different media. Compared with other types of seals, O-rings have the following advantages:
1, suitable for a variety of sealing forms: static seal, dynamic seal
2, suitable for various uses of materials, dimensions and grooves have been standardized, strong interchangeability
3, suitable for a variety of sports: rotary motion, axial reciprocating motion or combined motion (such as rotating reciprocating combination motion)
4, for a variety of different sealing media: oil, water, gas, chemical media or other mixed media
Through the selection of suitable rubber materials developed by Dongguan Rubber Materials and appropriate formula design, it can effectively seal oil, water, air, gas and various chemical media. Wide temperature range (-60°C～+220°C), pressure up to 1500Kg/cm2 (used with reinforcement ring) when fixed. O-ring design is simple, compact structure, easy assembly and disassembly, its sectional structure is extremely simple, and has a sealing effect, reliable sealing
