Nitrile (Lip code: R) is the most commonly used sealing material as nitrile is excellent with most mineral oils and greases. Variations are available for use with fuels, industrial fluids and highly compounded lubricants. Nitriles are recommended for operation at temperatures from -40° ~ 250°F (-40° ~ 121°C). Nitrile also works in dry running applications but only for intermittent periods. Some water based fluids however, such as some cutting fluids, can destroy the nitrile/plain steel bond when operating temperatures exceed 150°F (66°C). Please refer to pages 6A thru 15A in attached PDF catalog for chemical compatibility charts listed in alphabetical order

Bore-Tite® is a green tinted water based acrylic polymer. This green pliable sealant is applied to the outer case of select SKF seal part numbers and helps fill small imperfections in the housing bore when the seal is pressed into posistion. Bore-Tite® can withstand heat up to 400°F (204°C). It is resistant to most oils, greases, gasoline, mild acids, mild alkalis, aliphitics, salts and glycols. Bore-Tite® is NOT recommended with aromatics, ketones and alcohols; however splash contact that is wiped off will have little or no effect. The Bore-Tite® coating is .001 ~ .003" (.025 ~ .076 mm) thick but is not accounted for in the seals specified outer diameter
