Product Description

Rubber O ring

The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons.
O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable, and have simple mounting requirements. They can seal tens of megapascals (thousands of psi) of pressure.

Product Features:

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

Product Features:

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)

Related Products

Silicone 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)

EPDM O Ring

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 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
