??O-ring applications is very broad, mainly because rubber O-ring seal can be applied to dynamic and static seal, but it also can be used with other sealing devices. In real life, almost all major rubber material can be used to build the O-rings, rubber O-ring production process is not much technical content of the surface, in fact, require a number of high-quality O-ring elements:

??High quality O-rings What are the advantages?

??(1) up to judge from the appearance of high-quality O-rings, hand feels very smooth and no irregularities, no glitches neat torn edge, no scratches, the whole appearance of clean and shiny, rounded shape.

??(2) to determine the O-ring is not the quality standard has two main products of resilience and resistance to permanent deformation. Since the rubber O-ring seal is a typical extrusion, so there is no good resilience and resistance to permanent deformation will greatly reduce the sealing performance.

??(3) from the O-ring quality is concerned, now mostly sealed enterprises in order to attract customers and improve the quality of O-rings, thereby introducing some equipment abroad, using imported raw materials, so now after the many products produced with talk scent, pungent taste before contrast, production of rubber and plastics now O-ring can be further customers.
