Product Description

Product Description

The O-ring Seal

The O-ring is suitable to be installed on various mechanical equipment to seal at the specified temperature, pressure and different liquid and gas media in the static or moving state. Various types of sealing elements are widely used in machine tools,ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various instruments and meters.
O-ring is mainly used for static seal and reciprocating seal. When used for rotary motion sealing, it is limited to low-speed rotary sealing device. The O-ring is generally installed in the groove with rectangular section on the outer circle or inner circle to seal. The O-ring still plays a good role in sealing and shock absorption in the environment of oil resistance,acid-base, wear, chemical erosion and so on. Therefore, O-ring is the most widely used seal in hydraulic and pneumatic transmission system.

FKM, o-rings(Fluorocarbon)

*Service Temperature
For general type FKM  the service temperature is better limited to approximately from -26 C  to 232 C  in static applications, though the service temperature can arrive to 275 C at short time  In dynamic applications, it is suitable between -15 C and 200 C. 
*Application
Because FKM has excellent resistance of high temperature, oil, solvent, flame, chemicals and weathering, it is usually applied in automotive, chemical processing, aerospace and many other industries.
 

NBR orings(nitrile butadiene rubber)

*Service Temperature
For NBR the service temperature can be designed from -55 C to 100 C or up to 130 C depending on differenacrylonitrile content and formula.
*Application
NBR compounds have excellent resistance to abrasion, non-polar oils and solvent, water and permeation (higher acrylonitrile content will be better). NBR also can be used in conditions of dilute acids, alkalis and salt solution at low temperatures.

 

Silicone Rubber o ring 

*Service Temperature
For Silicones the service temperatures are from -60 C to 225 C. Some special types can be used in extreme temperature up to 300 C and down to -100 C.
*Application
Silicone rubber performs well under environmental and temperature extremes. It is usually applied in automotive and aerospace industries where flexibility and longevity are important. It is also a suitable material for parts that need food grade for food handling equipment and appliances.

Application

·applicable to a wide range of pressure, temperature and clearance

·generally, the required groove space is small and light
·under correct service conditions, the service life of O-ring can reach the material aging limit
·O-ring seal failure is generally gradual and easy to find and judge
·the price is generally lower than other sealing forms
