Silicone material
*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 FDA approval for food handling equipment and appliances.
We supply NBR O Ring kit , FKM O Ring kit , Silicone O Ring kit , EPDM O Ring kit etc.
Every material has its advantages .You can choose as your requirements .
For the o rings in the box , you can also choose sizes what you need.And the color of the box ,
you can choose what you like .
Peculiarity Of O Ring Cord:
1) NBR O Ring kit:Good chemical resistance to mineral oils and greases,hydraulic
oils H, HL, HLP,non-inflammable hydraulic pressure fluids HFA, HFB, HFC to approx.
+50°C and water to max. +80°C.
2) FKM O Ring kit: Good chemical resistance to mineral oils and greases, synthetic
oils and greases,engine, transmission and ATF oils to approx. +150°C
3) EPDM O Ring Cord:
Good resistance to hot water and steam, detergents, caustic potash solutions, silicone
oil and greases,many polar solvents, and many diluted acids and chemicals, along with
a high level of ozone resistance.
4) Silicone O Ring kit
Good resistance to water (up to 100 °C), aliphatic engine and transmission oils, animal
and plant oils and fats..
The below is the contrast of different material for o ring kit
