Molykote® 111 Compound is a heavy-consistency, silicone‑oil-based NLGI Grade 3–4 lubricant and sealant ideal for valves, O‑rings, and gaskets in demanding temperature and water‑contact applications.
Molykote® 111 Compound is a heavy-consistency silicone compound formulated to deliver long-term sealing and lubrication under extreme pressure and temperature fluctuations. It is highly effective in preventing water ingress and resisting degradation in both hot and cold water, as well as many chemical environments. Its compatibility with a variety of elastomers and plastics makes it a go-to solution in industrial, municipal, and food-grade processing systems.

Poor electrical stability from conventional lubricants Insufficient anti-stick performance or seizure Inadequate electrical resistance Leaks, poor sealant, or failures in valve lubricant Prevents valve leakage and seal failures in vacuum/pressure systems Reduces sticking, galling, and scoring by providing stable lubrication under extremes Resistant to wash-out, weathering, oxidation, and chemical attack
Control, pressure, water-softener, and faucet valves O‑rings and gaskets in food & beverage, municipal water, and chemical-processing equipment Sealing interfaces in vacuum, pressure systems, and outdoor/shipboard applications Damping dashpots in electronics and electrical insulated components Rubber/plastic seal lubrication during assembly which prevents tearing
Proper lubrication within the pulp & paper industry is critical. With extreme temperatures, harsh chemicals and near 24/7 production cycles the right lubricant can make or break a facility. The MOLYKOTE® portfolio of oils, greases and pastes help extend equipment life and increase reliability.
The Oil & Gas Industry truly powers all other industries. Therefore, it is critical that these facilities are kept operating at peak performance and protected with reliable and robust lubrication. Learn how the MOLYKOTE® Portfolio brings protection & long-term reliability here!
