??Rubber O-ring What are the advantages

??Rubber O-ring seal compared with other types, it has the following advantages:

??1, for a variety of seal forms: static seals, dynamic seals, suitable for various uses materials, dimensions and groove are standardized, interchangeable

??2, for a variety of motion: rotation, reciprocation, or a combination of axial motion (for example, a combination of rotational reciprocating motion)

??3, for a variety of different sealing medium: oil, water, gas, chemical media or other mixed media. By appropriate choice of rubber material and proper formulation, to achieve the oil, water, air, gas and various chemical mediators effective seal. Wide temperature range (- 60 ? ~ + 220 ?), fixed using a pressure of up to 1500Kg / cm2 (and reinforcing ring and use).

??4, simple design, compact, easy assembly and disassembly. Rubber O-ring cross-sectional structure is extremely simple, and there is self-sealing, reliable sealing performance. Because of the rubber O-ring structure itself and the installation site is extremely simple and has become standardized, so it is very easy to install replacement.

??5, material varieties. Can be selected according to different fluids: There nitrile rubber (NBR), Viton (FKM), silicone rubber (VMQ), ethylene-propylene rubber (EPDM), chloroprene rubber (CR), butyl rubber (BU), poly tetrafluoroethylene (PTFE), natural rubber (NR), etc.

??6, low cost

??7, dynamic friction is relatively small
