👉 The Parker fluid, also known as the Parker slip or Parker slip fluid, is a specialized lubricant used primarily in high-speed and high-temperature applications. It was developed by John Parker in the 1930s to address the limitations of conventional lubricants, which often failed under extreme conditions due to poor thermal stability and inadequate film formation. The Parker fluid consists of a unique blend of additives, including molybdenum disulfide (MoS2) and polytetrafluoroethylene (PTFE), which form a protective tribofilm on metal surfaces, reducing friction and wear even at elevated temperatures. This makes it particularly effective in aerospace, automotive, and industrial machinery where traditional lubricants would degrade or fail. The fluid's superior performance stems from its ability to maintain a stable lubricating film under harsh conditions, significantly extending the lifespan of components and improving efficiency.
