Product Description
What is an o-ring? An o-ring is a simple and versatile ring-shaped packing or sealing device with a circular cross section (from which the "O" in its name is derived). The purpose of using O-ring seals is to prevent leakage and loss of liquids or gases. They simplicity, convenience, and small installation space. As long as the groove design and material selection are correct, and the operating conditions are within the temperature range of the rubber material, the seal can have a long-term sealing effect in the static or dynamic seal.

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.
FKM, o-rings(Fluorocarbon)*Service Temperature
For general type Viton 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.
Silicone Rubber o ring (Q, MQ, VMQ, PVMQ)*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.
PU o-rings(Polyurethane)*Service Temperature
-45 to 120 °C
*Application
PU displays higher mechanical strength, high abrasion, wear and extrusion resistance, high pressure load capacity, as well as a high tear and elongation at break resistance.
PU is suitablefor for application in mineral oils and greases, hydraulic oils, silicone oils and greases, highly non-flammable hydraulic fluids HFA and HFB and water uo to 50ºC.
PTFE O-Rings*Service Temperature
PTFE's mechanical properties are low compared to other plastics, but its properties remain at a useful level over a wide temperature range of -100°F to +400°F (-73°C to 204°C).
*Application
PTFE is the common sealing material used for making wear ring, backing-up ring, o ring, gasket, etc. It can be found in metallurgy machinery, petrochemical machinery, engineering machinery, and light industrial machinery.
Ethylene Propylene Rubber (EPM, EPDM) *Service Temperature
For EPDM the service temperature can be designed from -55 C to 125 C or up to 150 C (for peroxide cured systems).
*Application
In phosphate-ester based hydraulic fluids and glycol based brake fluids systems Ethylene Propylene Rubber is good choice for sealing parts. EPDM is also is usually used in hot water or steam applications up to 150 C.
