Lubricants and Penetrants


993 products found

Lubricants and penetrants add a slippery film or coating on machinery, tools, or parts to reduce wear and friction between metal surfaces and keep the equipment running smoothly. Lubricants are typically low- to medium-viscosity fluids that are applied to bearings and other moving parts before installation to prevent future wear and tear. Penetrants are low-viscosity fluids that are applied to parts after they're installed. These penetrating solvents seep into threads and other tight spaces to help unstick seized or stuck components like nuts or bolts or to relubricate moving parts. Specialty lubricants and penetrants are used for specific applications, like preventing corrosion, loosening material from molds or casts, or maintaining chain, cable, and wire rope.
