HNBR O-ring

ERIKS suggests HNBR O-ring for demanding applications

The Hydrogenated Nitrile Butadiene Rubber (HNBR) O-ring has quickly grown in importance over the last years, due to its excellent cost-performance balance and use in highly demanding applications such as automotive, industrial applications which require high performance.

HNBR O-ring meets higher temperatures than standard NBR

The HNBR O-ring has recently been developed to meet higher temperatures than standard NBR while retaining resistance to petroleum based oils. The HNBR O-ring has a temperature range from -30°C to +150°C (-20°F to +302°F).

HNBR O-ring has excellent resistance to oils and chemicals

Obtained by hydrogenating the nitrile copolymer, the HNBR O-ring fills the gap left between NBR, EPDM and FKM elastomers where high temperature conditions require high tensile strength while maintaining excellent resistance to oils and chemicals. 

Resistance of the HNBR O-ring

The HNBR O-ring is resistant to the following media:

  • Biological oils
  • Motor oils
  • Lubricating oils
  • Miniral oil based hydraulic fluids
  • Oil/amine mixtures
  • Sour gas
  • Dilute acids and bases
  • Oxidized fuels 
  • Diesel fuel
  • Vegetable and animal fats
  • Ozone
