Applications & Uses

Applications

NovagardG661 is truly a general purpose compound. It is most frequently used as a valve and O-ring lubricant; however, the material’s unique dual nature, lubricity, and sealing, supports a long list of both past and current applications. Applications range from a valve and O-ring lubricant in small, hydraulic piston assemblies to a high vacuum sealant in laboratory services.

Restrictions

Do not use in or around highly oxidative chemicals such as liquid oxygen, or peroxides. Not recommended for surfaces that are to be painted.
