High quality 30-90 shore hardness FKM NBR EPDM Silicone O Ring
Rubber Seal O-Ring
Description of the sealing ring
Advantage: excellent resistant to gasoline and Fat hydrocarbon oil, second
only to TR, ACM and FKM, better than other general rubber. Good
heat resistance, good air tightness, abrasion resistance and water
resistance, strong cohesive force.
Disadvantage: poor cold resistance and ozone resistance, low strength and bad
flexibility, poor acid resistance, bad electrical insulation and
polar solvents resistance.
Operating Temperature: about -40°C~+120°C.
Application: mainly used in manufacturing all kinds of oil-resistant products,
such as rubber hoses and seals, etc.
ORK offers the seal industry's largest inventory of o-rings, which
includes every standard AS568 and ISO 3601 size, and the following:
- Inside Diameter from 0.031 in (0.794 mm) to 26.0 in (66.04cm)
- Outside Diameter from 0.094 in (2.38 mm) to 26.5 in (67.31cm)
- Cross Section from 0.031 in (0.794 mm) to 0.250 in (6.35mm)
In addition to standard imperial and metric sizes, ORK also carries
a wide variety of non-standard sizes. With over 8,000 different
o-ring sizes in-stock, we have exactly what you are looking for and
