O-RING
Product Details
It is characterized by its excellent mechanical strength and resistance against friction/oil. But, It may be fragile to the oils that have chemical activation like ultra-pressure additive.
Urethane Rubber
U565
It is the most excellent material for resistance against weather/freon gas.
Chloroplene Rubber
M352
It is the excellent material for chemical-resistance and durability, and is characterized by allowing no gas transmission. But, don't use it for mineral oil.
Butyl Rubber
B466
It is the material that has excellent resistance against vegetable oil and hot water. But, don't use it for mineral oil.
Ethylene Propylene Rubber
E617
It has the same resistance against oil, chemical and heat as F422, and excellent for compression and twist.
Fluorine Rubber
F201
It is the excellent material especially for heat/water resistance, and suitable for cylinder and liner use.
Silicon Rubber
S637
It has almost the same oil-resistance as A305, and especially excellent for cold-resistance.
NBR
A980
It is the material that has excellent resistance against internal-fuel oil, and especially most suitable for gasoline.
NBR
A908
Other Materials
E of 4
It has better heat-resistance than NBR, and especially has excellent oil-resistance against engine oil, gear oil and torque converter(hydrotype automatic transmission).
Acryl Rubber
T302
D of 4
It is the material that can be used for wide range of application among the synthetic rubbers having the most excellent resistance against oil, chemical and heat.
Fluorine Rubber
F422
C of 4
It is the material that can be used for widest range of temperatures among the synthetic rubbers having excellent heat/cold resistance.
Silicon Rubber
S503
3
It is the material having the most resistance against animal/vegetable oil such as ethylene glycol and brake oil.
Styrofoam Rubber
R189
2
It is the material for general fuel use having excellent resistance against fuel oil such as kerosene and diesel.
NBR
A122
B of 1
Even if it has almost the same property as A305, it has stronger hardness than A305, and is the excellent material in pressure-resistance.
NBR
A105
A of 1
It is the most representative material and can be widely used thanks to its oil-resistance and heat-resistance property.
NBR
A305
