    Product Description

  • Nitrile (Lip code: S) is the most commonly used sealing material as nitrile is excellent with most mineral oils and greases.
  • Offers desirable "low swell" properties across many hydrocarbon fluid types.
  • Variations are available for use with fuels, industrial fluids and highly compounded lubricants.
  • Nitrile works in dry running applications but only for intermittent periods.
  • Some water based fluids such as certain cutting fluids, can destroy the nitrile/plain steel case bond when operating temperatures exceed 66°C (150°F)
  • Nitrile exhibits poor ozone resistance.
  • Poor resistance to lubricants containing sulphur, EP additives, or oxygenated hydrocarbons.

  • Rubber cover over a metallic core offers an excellent combination of sealing ability and corrosion resistance.
  • The rubber elastomer outer covering tolerates thermal expansion as well as roughness in the housing bore.
  • Because of the rubberized covering on the seal, there will be no fretting/galvanic corrosion of the metal bore that the seal is pressed into.
