Introduction to the performance of common materials

Fluoro rubber O-rings: high temperature resistance, abrasion resistance, chemical resistance, ozone resistance, low air permeability, low compression set, but not steam resistance, the service temperature is -20 degrees to 240 degrees.

Nitrile rubber O-rings: cheap, oil resistance, waterproof, abrasion resistance, temperature -40 degrees to 120 degrees, not suitable for direct sunlight

Silicone O-ring: environmentally friendly, can meet FDA food grade, medical grade, ozone resistant, can be exposed to direct sunlight, dynamic sealing is not recommended, not oil resistant, not suitable for water vapor, the use temperature is -68 degrees to 200 degrees. The color can be customized according to the color card number.

EPDM O-rings: steam resistant, ozone resistant, weather resistant, not resistant to certain oils, consult us for details. The operating temperature is -54 degrees to 180 degrees.

Scope of application

O-ring is suitable for installation on various mechanical equipment, and plays a sealing role in static or moving conditions in the specified temperature, pressure, and different liquid and gaseous media. In machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and all kinds of instrumentation, a large number of types of sealing components are used. O-rings are mainly used for static sealing and reciprocating motion sealing. When used for rotary motion sealing, it is limited to low-speed rotary sealing devices. The O-ring is generally installed in a rectangular groove with a rectangular cross-section on the outer or inner circle to play a sealing role. The O-ring still plays a good role in sealing and shock absorption in oil, acid and alkali, abrasion, chemical attack and other environments. Therefore, O-rings are the most widely used seals in hydraulic and pneumatic transmission systems, The O-type sealing ring has its own sealing effect, does not make periodic adjustments, and the sealing can not be affected by the direction of movement when used for sliding sealing, and the size is small and easy to use at the same time, because the adaptability of the sealing ring is large, so the range of application is very wide, but it is easy to deform under the pressure peak to reach a certain pressure, and there is the possibility of extrusion void, which is more used in aviation and water conservancy engineering.
