O-ring seals and other types of comparison, has the following advantages: - for a variety of seals in the form: static seals, dynamic seals materials for various purposes, sizes, and grooves have been standardized, interchangeable - for more kinds of movement pattern: rotation, axial reciprocating movement or combination of movements (such as rotary reciprocating motion combined) - for a variety of sealing medium: oil, water, gas, chemical, or other media, mixed media by appropriate choice of materials and rubber appropriate formulation, to achieve the oil, water, air, gas and chemical media and effective seal. Wide temperature range (- 60 ℃ ~ + 220 ℃), fixed up the pressure when used 1500Kg/cm2 (with the reinforcement ring and use). - Design a simple, compact, easy assembly and disassembly O-ring cross-section structure is extremely simple, and there is self-sealing, sealing performance and reliable. As the O-ring and install parts of the structure itself is extremely simple, and has become standardized, so installation is very easy to replace. - Material varieties can be selected according to different fluid: a nitrile rubber (NBR), Viton (FKM), silicone rubber (VMQ), ethylene-propylene rubber (EPDM), chloroprene rubber (CR), butyl rubber (BU), polytetrafluoroethylene (PTFE), natural rubber (NR), etc. - low cost - a relatively small dynamic friction
