G661 can be used as an alternative to Molykote 111 Compound (Dow Corning’s DC111).

Versilube G661 is from our family of general-purpose silicone greases thickened with inorganic fillers for lubrication and insulation, which are resistant to oxidation and thermal degradation. G661 seals and protects electrical connections above and below ground. The material’s unique dual nature, lubricity, and sealing, supports a long list of applications.

G661 and Novagard’s G662 are most frequently used as a valve and O-ring lubricant, and either can be used as an alternative to Molykote 111 Compound (Dow Corning’s DC111).
