DuPont Molykote® 111 Silicone Compound 100g – Valve Lubricant & Sealant
DuPont Molykote® 111 Silicone Compound 100g is a premium silicone lubricant and sealant engineered to protect, lubricate, and seal rubber, plastic, and metal components in demanding industrial and commercial applications. Its advanced silicone formulation delivers outstanding water resistance, excellent sealing performance, and long-lasting lubrication without hardening, melting, or washing away.
Maintenance professionals, engineers, and technicians use Molykote 111 to lubricate control valves, pressure plug valves, faucet valves, water softener valves, O-rings, gaskets, seals, and vacuum systems. The compound creates a durable protective barrier that minimizes friction, prevents sticking, and extends the service life of sealing components.
Molykote 111 performs reliably across a wide operating temperature range of -40°C to +200°C, making it suitable for both low-temperature and high-temperature environments. Its low vapor pressure and low volatility ensure stable performance over extended periods, even in vacuum and pressure systems.
The compound also protects outdoor electrical equipment, underground cable connections, meters, transformer gaskets, and equipment enclosures from moisture, weathering, and water wash-out. Because it contains no drop point, it does not melt or run under normal operating conditions, providing consistent lubrication and sealing performance.
In addition to industrial machinery, Molykote 111 is compatible with many plastics and elastomers, making it an excellent choice for maintaining rubber O-rings, seals, and gaskets in plumbing systems, food processing equipment, electrical installations, and marine applications.
