HNBR (hydrogenated nitrile rubber) has better oil and chemical resistance than standard NBRs (nitrile rubbers) and can also withstand much higher temperatures. Like NBR, this type of elastomer has excellent resistance to oils and fuels but it also has excellent resistance to many chemicals, heat (steam / hot water) and ozone. The mechanical properties like tensile and tear strength, elongation, and abrasion resistance are also excellent. Furthermore, HNBRs have good dynamic behavior at elevated temperatures. The typical working temperature range is -25°C to +160°C (-40°F to +320°F).
Note. We do not offer a grease sachet as this is a confusing area. Some manufacturers advise no grease. Others do but what type to use. Some use fork oil. The choice is yours.
