Silicon Rubber O-Ring/ HNBR O-Ring/ FKM O Ring

Specifications:
We can provide more than 1000 different sizes at AS568, BS, JIS series and other national standard O rings in Nitrile (NBR), Silicone(MVQ), EPDM, HNBR, Viton (FKM), Neoprene,CR materials 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. 
 
Rubber NBR O Ring
 
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

Rubber Viton O Ring  
 
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)

Rubber EPDM O Ring
 
Excellent resistance to weathering and ozone, water and steam, with good performance in castor and some phosphate ester based fluids. Its low and high temperature capability is good, having excellent resistance to set with good resilience. Also high temperature braking systems employing castor based fluids for mouldings subjected to weathering and ozone and for seals in chemical plant due to its good chemical resistance.
EPDM is particularly useful when sealing phosphate-ester hydraulic fluids and in brake systems that use fluids having a glycol or silicone base. This results in a highly fluorinated elastomeric compound with exceptional temperature resistance, compatibility with a wide range of aggressive chemical combinations and outstanding resistance to permanent deformation.
Chemical resistance
Hot water and steam up to 149°C with special compounds up to 260°C
Glycol based brake fluids (Dot 3 & 4) and silicone-based brake fluids (Dot 5) up to 149°C
Many organic and inorganic acids
Cleaning agents, sodium and potassium alkalis
Phosphate-ester based hydraulic fluids (HFD-R)
Silicone oil and grease
Many polar solvents (alcohols, ketones, esters)
Ozone, aging and weather resistant

Rubber Silicon O Ring
 
 
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.
Chemical resistance
Dry heat
High - aniline point oils
Chlorinated DI - phenyls
Food processing applications
Excellent ozone resistance.
Water (Low temperature only)

Rubber HNBR O Ring
 
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
