The O-Ring Kit can be used for HYUNDAIexcavator.

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 -40°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)

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.

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.

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.
