Engage High-Tech Lubricant with PTFE provides lubrication over a wide temperature range of -70° to +480°F (-57° to +249°C), company officials said. Engage penetrates through rust and water to coat, lubricate and protect metal surfaces. Its high dielectric strength of 41,000V/2.5mm allows Engage to be used on de-energized electrical connectors to flush out dirt, debris and moisture while leaving a protective corrosion-inhibiting film that will not wash off.
