Molykote/Dow Corning 111 Valve Grease - 1kg Container
MOLYKOTE® 111 Compound is a high-performance silicone-based lubricant and sealing compound developed for the long-term protection of valves, seals, O-rings, gaskets, and other elastomeric components. Recognised as an industry-standard solution, it delivers reliable lubrication and sealing performance across a wide range of industrial, commercial, and potable water applications.
Formulated from premium silicone oil with an inorganic silica thickener, MOLYKOTE® 111 provides excellent adhesion and remains firmly in place even when exposed to moisture, pressure, or challenging environmental conditions. Its exceptional resistance to water washout helps maintain seal integrity and lubrication where conventional greases may fail.
Suitable for use with many plastics and elastomers, the compound protects against wear, sticking, and environmental degradation while supporting smooth operation of sealing components. Its wide operating temperature range of -40°C to +204°C ensures dependable performance in both low-temperature and high-temperature environments.
MOLYKOTE® 111 Compound is widely used throughout water treatment systems, valve assemblies, electrical enclosures, marine equipment, vacuum systems, and industrial process applications where long-lasting sealing and lubrication are essential.
