Rubber O-ring

Rubber O-ring seals are suitable for installation on various mechanical equipment, and play a sealing role in static or moving states under specified temperature, pressure, and different liquid and gas media. Various types of sealing elements are widely used in sanitary ware, ships, automobiles, hardware, electronics, toys, electrical appliances, aerospace equipment, machinery, and various instruments and meters. Rubber O-rings are mainly used for static sealing and reciprocating motion sealing. When used for rotary motion sealing, it is limited to low-speed rotary sealing devices. The rubber O-ring is generally installed in a groove with a rectangular cross-section on the outer circle or the inner circle to act as a seal. Rubber O-ring seals still play a good role in sealing and shock absorption in environments such as oil resistance, acid and alkali, abrasion, and chemical erosion. Therefore, the rubber O-ring is the most widely used seal in hydraulic and pneumatic transmission systems. Advantage Compared with other types of sealing rings, the rubber O-ring has the following advantages: 1. Suitable for various sealing forms: static sealing, dynamic sealing, Suitable for a variety of materials, dimensions and grooves have been standardized, strong interchangeability 2. Suitable for a variety of motion modes: rotary motion, axial reciprocating motion or combined motion (such as rotary reciprocating combined motion) 3. Suitable for a variety of different sealing media: oil, water, gas, chemical media or other mixed media Through the selection of suitable rubber materials and proper formula design, the effective sealing effect on oil, water, air, gas and various chemical media can be realized. The temperature range is wide (- 60 ℃ ~ 220 ℃), and the pressure can reach 1500Kg/cm2 in fixed use (used together with the reinforcing ring). 4. Simple design, compact structure, easy assembly and disassembly The section structure of the rubber O-ring is extremely simple, and has a self-sealing function, and the sealing performance is reliable. Since the structure of the rubber O-ring itself and the installation part are extremely simple and standardized, installation and replacement are very easy. 5. Many kinds of materials Can be selected according to different fluids: nitrile rubber (NBR), fluorine rubber (FKM), silicone rubber (SIL), ethylene propylene diene monomer (EPDM), neoprene rubber (CR), natural rubber (NR) hydrogenated Nitrile rubber (HNBR), butyl rubber (IIR), silicone fluororubber (FLS), etc.
