Abstract
This invention relates to compositions containing a sulfur containing antiwear/extreme pressure agent, basic nitrogen compound or a mixture thereof together with a hydrocarbyl mercaptan. The composition may additionally contain a phosphorus or boron antiwear or extreme pressure agent, a dispersant or an overbased metal salt. The invention also relates to lubricants, functional fluids, and concentrates containing the same. Seals, e.g. nitrile, polyacrylate, and fluoroelastomer, in contact with these composition have reduced deterioration. With the use of these compositions, lubricants, and functional fluids, the seals' useful life is extended.
