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 applications. High-grade petroleum oils provide optimum lubrication under extreme temperatures and humidity. Formulated solvents soften and remove dirt and contaminants, while special additives displace moisture and prevent rust and corrosion. Formulated with PTFE.
