Liquid silica gel manufacturers tell you that O-ring, referred to as O-ring, is a circular rubber ring, its shape is the most simple, easy to manufacture, low cost, is the most widely used in hydraulic and pneumatic systems of a seal. O-ring is a kind of extrusion seal, has good sealing, can be used for static seal, also can be used for reciprocating motion seal, not only can be used alone, but also is a basic part of many combined sealing devices.

O silicone rubber sealing ring

O-shaped silicone rubber sealing ring is made by hot pressing rubber with metal mold after vulcanization treatment. For large size can first make a long strip, and then according to the need to cut into a certain length, and then the two ends of the adhesive together.

Compared with other shapes of mechanical seals, O-shaped rubber sealing ring has small size, simple structure, light weight, convenient assembly and disassembly; There is a self-sealing effect, often only one seal can complete the sealing; The use of single O-ring, bi-directional sealing; Good sealing performance, static and dynamic seal can be used, used as a static seal can almost do no leakage, for reciprocating movement, in the reciprocating stroke sealing performance unchanged, leakage is very small, only at a higher speed when some leakage; Motion friction resistance is very small, can also adapt to the occasion of pressure alternation; Dimensions and grooves have been standardized, low cost, easy to use and outsourcing; The range of use is very wide, liquid silica gel products feel that if the material is chosen properly, it can meet the requirements of all kinds of media and various movement conditions, the working pressure can be from 1.333×105Pa vacuum to 400MPa high pressure (dynamic seal up to 35MPa); Temperature range from -60℃ to 200℃ and other advantages.
