Morris Compounded Steam Cyl Oil 680

Compound Steam Cylinder Oils 460 and 680 are for use in most Locomotives and Stationary engines working with either saturated or superheated steam. They are produced from special cylinder stock treated with fatty compounds to provide superior lubrication even if wet conditions are encountered. The fatty compounds form emulsions which spread the oil on the internal surfaces, providing a strong lubricating film where needed to protect bores and valves. This is particularly important where very wet steam has to be handled at the cylinders, or water treatment chemicals are carried with the steam
