Rubber o rings are standard seal.

Nowadays , There are many manufactures which can provide standard seal, but the quality is difference, cheap as well as satisfy us are less. I suggest you do following things if you want to buy o rings.

Understanding the rubber o ring: the situation of sealing is Static or dynamic; What’s the temperature if work for a long time, what’s limit temperature; Whether the require for high pressure, how much, and to choose the hardness of rubber o ring seal; gaseous medium or liquid medium.

Besides, choosing materials of o ring is also very important, Because materials influence the products directly.

1.Whether the material sealing, resilience and compression is good

2.Whether the price is moderate, whether it is easy to form;

3.Whether Anti aging ability is strong, life is long

4.Whether the wear resistance is good, the friction is small

5.In a particular medium (acid, alkali, water, steam, oil, etc.) whether to maintain the volume does not expand or expand smaller

6.Does not appear to soften or break down the phenomenon in high temperature,  does not harden or brittle crack in low temperature

   Rubber sealing ring features: the structure is simple, has been standardized; installation occupies small space; stable performance, low price; widely used in water, oil, gas and a variety of chemical solvents sealed;

   Rubber sealing ring, a sealing ring in by external stress, the stress in a certain range does not occur permanent deformation and meet the conditions, the better is the synthetic rubber.: FKM fluorine rubber /VITON DuPont, SIL silica gel, the NBR , EPDM, HNBR, PU and other commonly used;
