    Product Description

  • Polyacrylate (Lip code: N) are well suited for use with extreme pressure (EP) lubricants and have higher resistance to oxidation and ozone than nitrile.
  • Resistant to sulphur commonly used as a grease additive.
  • Polyacrylate elastomers have good compatibility with higher temperatures up to 149°C (300°F), and even to 177°C (350°F) with some fluids.
  • They should not be used alongside water or other aqueous solutions.
  • Does not perform at temperatures below -40°C (-40°F)
  • Polyacrylates are not recommended for dry running applications.

  • Many of Nationals metal cased seals are offered with Redi-Coat® rubberized coating which is applied over the seals bare metal case and helps fill in any minor bore imperfections upon installing the new seal.
