McLube MoS2-722 Penetrating Oil with Moly. Aerosol Spray & Bulk Packaging


McLube MoS2-722 is a low viscosity penetrating oil containing molybdenum disulfide (MoS2). It is particularly effective in freeing connectors frozen due to corrosion or chemical attack. Applied at assembly, reduces possibility of stuck connectors and need of cutting to free the parts.

Technical Data:

  • Color and appearance................Grayish-Black dispersion
  • Dispersing medium.....................Mineral Oil
  • Specific gravity............................0.85
  • Weight per gallon (lbs.)..............7.1

Application Method:

    Since McLube MoS2-722 contains solids which settle upon standing, agitation is required to properly disperse the solids from the bottom prior to use and periodically during use. The dispersed liquid can be applied by brushing, dripping, spraying or dipping. For application into narrow openings or onto small parts, an aerosol should be used with an extension tip. After application to a frozen or stuck part, the oil should be allowed to penetrate before attempting to separate the part.

Safety and Handling:

    The Material Safety Data Sheet for McLube MoS2-722 should be reviewed prior to using the product. Use only with adequate ventilation, especially in enclosed areas. This product is flammable, and thus the container should be kept away from heat, sparks and flame. Safety glasses and gloves are recommended when using this product.
