O-ring made of nitrile rubber (NBR) with dimensions 1.8X1.8 mm. Hardness 70 ° Shore (standard).
Nitrile rubber (NBR) can advantageously be used for hydraulic oils, vegetable oils, animal oils, acetylene, water, air, alcohol, fuels and many other media.
✔ Wide temperature range
✔ High and constant friction
✔ High abrasion resistance, even at high temperature
✔ Very good dynamic properties
✔ Permanent toward oils and acids
✔ Extraordinary antistatic properties of black nitril rubber (with kimcker)
