Morris Mainline 1000 Superheat Steam Cylinder Oil

Morris Mainline 1000 Superheat Steam Cylinder Oil is a premium non-staining steam cylinder oil developed specifically for full size steam engines operating on the national rail network and Sentinel S Type waggons where true superheat conditions are experienced on longer hauls up to 650°F. The incorporation of selected additives ensures saturated conditions on start-up or after prolonged stationary periods are correctly lubricated.

Locomotives operating under superheat conditions can cause lesser grades to form heavy carbonaceous deposits around piston rings and cylinders. These deposits — which can lead to accelerated wear — are virtually eliminated through careful selection of base oils, additives and precisely targeted quality control testing. Mainline 1000 has a higher level of Tallow compounding than the Morris Compound Steam Cylinder Oil range, making it the correct choice for true superheat applications above 230 psi.
