Nitrile (NBR) 70
The most common elastomer used for industrial grade O-rings. Compatible with most mineral based hydraulic fluids with a working temperature range from -40°C to 110°C.
Nitrile (NBR) 90
Harder than Nitrile 70 and hence suitable for use as a high pressure O-ring or back up washer.
Possessing the broadest chemical compatibility of any mainstream elastomer, its broad working temperature range of -35°C to 205°C and excellent mechanical properties make this an excellent high performance compound for use in hydraulic systems.
Silicone, EPDM, Neoprene
..and other specialty compounds are available in many sizes or to order.
