Advantages of the O-ring
The O-ring is widely used in life, such as furniture, household appliances, automobiles, fire fighting, pharmaceutical and so on. Especially compared with other forms of sealing ring has more advantages, the following is to check.
Compared with other types of sealing ring, O-ring has the following advantages:
1, suitable for a variety of sealing forms: static sealing, dynamic sealing, suitable for all kinds of materials, dimensions and grooves have been standardized, strong interchangeability
2, suitable for a variety of motion: 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 appropriate rubber materials and appropriate formula design, to achieve effective sealing effect on oil, water, air, gas and various chemical media. Wide range of temperature (-60¡æ~+220¡æ), fixed use of pressure up to 1500Kg/cm2 (with the reinforcement ring).
4, simple design, compact structure, convenient assembly and disassembly. O-type sealing ring section structure is very simple, and has self-sealing effect, sealing performance is reliable. Because the o-ring itself and the installation part of the structure is very simple, and has formed a standard, so it is very easy to install and replace.
5, material variety. Can be selected according to different fluids: butadiene rubber (NBR), fluorine rubber (FKM), silicone rubber (VMQ), ethylene propylene rubber (EPDM), chloroprene rubber (CR), butyl rubber (BU), polytetrafluoroethylene (PTFE), natural rubber (NR), etc
6, low cost
7, dynamic friction resistance is relatively small
Choosing the right seal ring is a key step. O-ring can adapt to most environments and has great advantages.
