Superior Lubricant Drip Bottle Tri-Flow Superior Lubricant provides twice the lubricating power of most competitive brands. Its light viscosity allows for deep penetration into hard to reach moving parts. High grade petroleum oils provide optimum lubrication under extreme temperatures (-60 to 475F) and humidity. Formulated solvents soften and remove dirt and contaminants, while special additives displace moisture and prevent rust and corrosion.
