The Oring is a section of circular rubber sealing ring, because of its section for the o -. So it was O shaped rubber sealing ring, also called the Oring. Began to appear in the middle of the nineteenth Century, when used as a steam engine cylinder sealing element. Because the price is cheap, simple manufacture, reliable function, and the installation requirements are simple, O ring is the most common seal with mechanical design. O ring to bear the pressure of tens of million Pascal (1000 pounds). O ring can be used in static applications, can also be used in the dynamic application of relative motion between the parts, such as the axis of the rotary pump and the hydraulic cylinder piston.
We can provide more than 1000 different sizes at AS568, BS, JIS series and other national standard O rings in Nitrile (NBR), Silicone(MVQ), HNBR, Viton (FKM), and so on.Hardness range from 40 to 90 Shore A.We can also supply many other non standard and colours (blue, brown, grey, red, white, yellow, green) o rings as your requirements.
Nitrile (or NBR) O-Rings are most commonly available and are cost effective. Ideal for use as seals on pumps, drive belts, and other general engineering applications.NBR is good for applications that need to withstand fats, Greases and high temperature (+70°C). Temperature Range -30°C to +120°C (avoid prolonged use at higher extremes)Suitable for: Many hydrocarbons, fats, oils gasoline, petroleum based hydraulic fluid etc.
Viton (FKM) O Rings have a low compression set and have high temperature and chemical resistance.
More expensive than NBR O Rings.
The terms FPM, FKM and Viton very often cause confusion and lead to incorrect interpretations. All of these designations actually stand for one single base material: fluoro rubber.Temperature Range -30°C to +200°C (avoid prolonged use at higher extremes)
Silicone possess excellent resistance to temperature extremes. Silicone's retention of properties at high temperatures is superior to other elastic materials. Silicone has poor tensile strength, tear resistance and abrasion resistance.
Dry heat
High - aniline point oils
Chlorinated DI - phenyls
Food processing applications
Excellent ozone resistance.
Water (Low temperature only)
Hydrogenated nitrile is a synthetic polymer that results from the hydrogenation of nitrile rubber (NBR). This gives it superior mechanical characteristics, particularly high strength, greater thermal stability and helps reduce extrusion and wear.
Chemical resistance
Aliphatic hydrocarbons
Vegetable and animal fats and oils
HFA, HFB and HFC hydraulic fluids
Dilute acids, bases and salt solutions at moderate temperatures
Water and steam up to 149°C (300°F)
Ozone, aging and weathering
