Damping greases are specialty lubricants. They reduce wear and seal out dust and moisture like tradional greases, but their primary function is to control motion and noise in mechanical and electromechanical devices. For example, the "velvet feel," silent operation, and the fact that lenses don't coast are all the work of damping greases on the focusing threads of binoculars, zoom lenses, and other optical instruments. The Fluorocarbon Gel 868 damping grease series is a new family of PTFE-thickened damping greases developed by Nye for high-shear, metal-on-metal components that have to operate smoothly and quietly for extended periods.
Nye Damping Grease Kit
This kit comes in a sturdy plastic carrying and storage case and includes five basic grades of Nye Fluorocarbon Gel 868 Damping Greases, ranging from a light viscosity Fluorocarbon Gel 868VL to a heavy viscosity Fluorocarbon Gel 868VH, each packaged in a 10cc plastic syringe. Also included are an ergonomically designed plunger and five twist-on stainless steel tips, along with product literature, technical data sheets and MSDS. The kit is an excellent tool for testing and trying various grades without having to purchase them individually. This kit sells for $89.95 (If you were to purchase each syringe separately, you would pay over $200.)
