Premium Steam Cylinder Oil, 220 grade, Compounded, 30ml Bottle

Application

Is used in displacement lubricators, i.e. mixed with steam, for the lubrication of steam engine cylinders in locomotives and stationary engines.

Not for general lubrication - see Lubricating Oil.

The 30ml plastic bottles come with a dropper (so the oil can be precisely squeezed out), are easy to refill and have a double safe childproof cap.

Benefits

Enhanced lubricating properties and high film strength provides good lubrication for medium and high pressure engines

The formulation is suitable for operations in superheated, dry and wet steam conditions.

NOTE: Modern steam oils contain about 4% tallow oil by volume.  It is this tallow oil that makes steam oil work in the hostile internal environment of the steam engine. In practice the producers use several compounds in steam oil to help stabilize viscosity and lubricity; hence the name compounded steam oil.  The color of steam oil is determined by the origin of the base oil and so it is imprudent to assess the viscosity of oil by its color. Lighter color steam oils are not necessarily of a lower viscosity than darker color steam oils.
