• be suitable for the temperature range intended.
• be water- and heat-resistant and non-separating.
• not create more than 8% swell in Buna N or Viton.
• not contain any grit, abrasive, or fillers.
• be slump-prefer NLGI-0 grade.
• not be corrosive to steel gears, balls, or roller bearings.
• have a dropping point above 316°F (158°C) for temperature ranges of -20°F to 150°F (-28°C to
65°C).
