Tri-Flow superior lubricant is a superior, light viscosity lube that allows for deep penetration into hard to reach moving parts. The aerosol spray action allows you to have a focused spray for even application. High-grade petroleum oils provide optimum lubrication under extreme temperatures (-60 to 475 degree Fahrenheit) and humidity. Formulated solvents soften and remove dirt and contaminants, while special additives displace moisture and prevent rust and corrosion. Formulated with P.T.F.E.
