#046  70D O'rings
ID 4-1/4 OD 4-3/8 x  CS 1/16
​​Common Names:
  • ​NBR (acrylonitrile butadiene rubber), Buna-N, Nitrile.
General Description:
  • ​Most commonly used general purpose o-ring material because of relative low cost, good mechanical properties, and basic resistance to many common lubricants. Specific physical and chemical resistances vary by compound formulation. B1000 is formulated to provide value with balance cost and performance. 
​ Features:
  • ​Relative low cost
  • ​Good/Excellent resistance to compression set and tear/abrasion. 
  • Good/Excellent resistance to many petroleum oils/greases, hydraulic fluids, alcohol, ambient water, silicone greases, Di-ester base lubricants and ethylene-glycol based fluids. 
  • Ozone, direct sunlight, UV, weathering, aromatic fuels, glycol-based brake fluids, polar solvents, nonflammable hydraulic fluids (HFD), aromatic/chlorinated hydrocarbons, ketones, esters, and aldehydes

​15 year shelf life

​Cure System:
  • ​Sulphur (Peroxide cured CPDs available with improved physical, chemical, and thermal properties)

​Service Temperature:
  • -30 to 250 oF (Additional CPDs available with -65oF and +275oF service temps)
