American standard O-ring is a rubber sealing ring,also known as AS568 standard O-ring.
The design of this sealing ring is very simple and practical, and it is the most widely used seal in hydraulic and pneumatic systems. The specifications and models of the American Standard O-ring follow the standards of the American National Standards Institute (AS568), which is suitable for a variety of industrial occasions requiring sealing, such as automobiles, ships, machine tools, aerospace and other fields. Its main role is to achieve seal through elastic deformation, which can be used for static seal and dynamic seal, such as rotary pump shaft and hydraulic cylinder piston. O-rings can withstand a variety of liquid and gas media, including wear resistance, oil resistance, high temperature and pressure resistance, chemical corrosion resistance and strong acid and alkali resistance. When designed and installed, The O-ring is usually installed in a groove with a circular cross-section, creating a sealing effect by compression of two or more components. Because of its low cost, simple manufacture, reliable function and low installation requirements, The American standard O-ring has become one of the most common sealing mechanical designs.
The specifications and characteristics of the American standard O-ring are mainly reflected in its size diversity and wide application, Its specifications and sizes cover from the small ID (inner diameter) 0.74 to the larger ID 215.27, with a variety of sizes to meet the needs of different applications. These sizes include but are not limited to 113.00×6.99, 120.02×6.99, 148.59×6.99, 177.17×6.99, etc., showing the flexibility of American standard O-ring in size designs , Lixu Rubber has all American standard O-ring molds, which provides a wide range of reference for customers to choose the size !
American standard O-ring features include:
Wide application range: American standard O-ring is suitable for various industrial sealing needs, such as automobiles, ships, motors, machine tools, machinery, aerospace, sanitary ware, electronic and electrical appliances, medical machinery, food machinery, mining machinery, agricultural machinery, precision instruments and so on. This is due to its simple and practical structure, which can play a sealing role in different liquid and gas medias.
A variety of material selection: American standard O-ring can be used in different materials, including NBR rubber, silicone rubber, EPDM rubber, fluorine(FKM) rubber, etc. These materials give O-ring wear-resistant, oil resistance, high temperature and high pressure resistance, chemical corrosion resistance, strong acid and alkali resistance characteristics, so that it can work statically for a long time under extreme conditions
Design flexibility: American Standard O-rings are designed with a variety of applications in mind, including static and dynamic seals, and can be used either as standalone sealing elements or as the basic component of a combined sealing unit. In addition, it also has a shock absorption effect, suitable for low speed turning density.
Standard internationalization: The American standard O-ring standard is not limited to the United States,Its standard size and design has been widely accepted and used internationally, to ensure its worldwide compatibility and interchangeability
In summary, American standard O-rings with its diverse specifications and sizes, wide range of applications, a variety of material options and design flexibility and other characteristics, have become one of the most widely used seals in hydraulic and pneumatic systems.
