Sovereign 460 Straight Steam Cylinder Oil

Sovereign 460 Straight Steam Cylinder Oil is a premium non-compounded steam cylinder oil from Morris Lubricants, refined to deliver exceptional film strength at very high temperatures. Providing reliable lubrication for bores and valves in steam engines utilising wet or dry steam, it offers superior oxidation resistance and low deposit forming characteristics under extreme conditions of temperature and pressure — making it a trusted choice for demanding steam applications.

Sovereign 460 has exceptional water separability properties, separating quickly and cleanly from water, and is particularly recommended for lightly loaded engines where steam condensation needs to be recovered. As a non-compounded oil it is the preferred choice over compounded products where steam is being recovered for use as boiler or process feed. Non-staining and safe on paintwork and brasses, Sovereign 460 meets the requirements of British Rail schedule number MT276.
