Sovereign 680 Straight Steam Cylinder Oil - 5L

Sovereign Straight Steam Cylinder Oils are refined to give film strength at very high temperatures, providing excellent lubrication where needed to protect bores and valves. These grades are noncompounded, have superior resistance to oxidation and have low deposit forming characteristics under extreme conditions of temperature and pressure. They also possess strong demulsification characteristics and therefore separate quickly and cleanly from water.
