HIGH VISCOSITY LUBRICANT U4 Chemical compatibility with O-rings, rubbers, & plastics

High viscosity lubricant U4 is a heavy duty industrial lubricant formulated for machinery operating under high loads and demanding conditions. These lubricants are designed to maintain stable viscosity across a broad temperature range while reducing friction, wear, and corrosion in mechanical systems. In equipment that contains O-rings, rubber seals, gaskets, and plastic components, lubricant compatibility should be evaluated to prevent swelling or degradation of sealing materials. Proper storage, contamination control, safe handling practices, and regular system monitoring help maintain lubrication performance and equipment reliability.
