Double acting seals, the sealing effect is achieved by the deformation of the section of the  O-Rings, and the deformation is determined by the depth of the installation groove.  Under pressure, the O-ring has a large surface tension like liquid, used for static  sealing more. It is only recommended for better conditions in dynamic applications.  System lubrication, pressure, temperature, sealing clearance, speed, medium and surface  quality of metal parts determine the service life of O-Rings. It is not recommended if the  lubrication is not sufficient during rotary motion.

O Ring description.


NBR(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.
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, (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. 

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 (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.

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 FDA approval for food handling equipment and appliances.


PU (Polyurethane)

*Service Temperature
-45 to 120 °C

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 50℃. 


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).


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).
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.






We recommended using a vernier caliper for measurement. Accurate to 0.01mm.

In addition to the standard size of o-ring, we can also custom non-standard size as required.
