O ring Details

Rubber O-rings are suitable for a wide range of mechanical equipment to seal against static or moving conditions at specified temperatures, pressures, and in different liquid and gaseous 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. Rubber O-rings are mainly used for static and reciprocating seals. For rotary motion seals, only for low speed rotary seals. The rubber O-ring is generally installed in a groove with a rectangular cross section on the outer or inner circle to seal. The rubber O-ring seal still plays a good role in sealing and damping in the environment of oil resistance, acid and alkali, grinding and chemical corrosion. Therefore, rubber O-rings are the most widely used seals in hydraulic and pneumatic transmission systems.

 

Advantages
Rubber O-rings have the following advantages compared to other types of seals:
1.Suitable for a variety of sealing forms: static sealing, dynamic sealing.
Suitable for a variety of materials, sizes and grooves have been standardized and interchangeable.
2.Suitable for a variety of sports: 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.
Effective sealing of oil, water, air, gas and various chemical media through the selection of suitable rubber materials and appropriate formulation design. The temperature range is wide (-60 °C ~ + 220 °C), and the pressure can be up to 1500Kg/cm2 in fixed use (combined with reinforcing ring).
4.Simple design, compact structure, easy to assemble and disassemble.
The rubber O-ring cross-section structure is extremely simple, and has a self-sealing effect, and the sealing performance is reliable. Since the rubber O-ring itself and the mounting structure are extremely simple and standardized, installation and replacement is very easy.
5.Many varieties of materials
It can be selected according to different fluids: nitrile rubber (NBR), fluororubber (FKM), silicone rubber (SIL), ethylene propylene diene monomer (EPDM), neoprene (CR), natural rubber (NR) hydrogenation Nitrile rubber (HNBR), butyl rubber (IIR), silicone rubber (FLS), etc.
6.Low cost
