The product can be used as a lubricant for rubber and plastic O-rings, water softener and faucet valves, valve stems for potable water, aircraft-vacuum systems, and electronic and ignition systems. Sealant uses include vacuum and pressure systems, equipment subject to washing and harsh environments, electrical-service entrances, and underground connections. The lubricant and sealant maintains a serviceable consistency from approximately 70 to 400°F.
