G661 and G662 are alternatives to DC111

If you are looking to replace Dow Corning's DC111, Novagard offers two alternatives: G661 and G662.

Novagard’s G661 and G662 are general purpose compounds that are ideal for sealing and protecting electrical connections above and below ground. Just like Molykote® 111 Compound, G661/G662 are most frequently used as a valve and O-ring lubricant.

Both Novagard silicone greases have a wide temperature range -40°C to 204°C (-40°F to 400°F) and excellent vacuum capabilities along with outstanding water resistance. In addition, G662 is certified to NSF Standard 61 for Drinking Water System Components.
