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.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.Please note that not all product images are representative of the item being shown but are similar in appearance.
