PerFluoroLube® AR555 Manufactured Exclusively with FOMBLIN Base Fluid


Product Overview

PerFluoroLube® AR555 is Manufactured exclusively with FOMBLIN Base Fluid. AR555 is a homogenous white grease having excellent rust inhibiting and solvent washout resistance properties. AR555 is suitable for lubricating mechanical parts requiring boundary (extreme pressure) lubricating properties

AR555 is suitable for use in severe operating conditions, high load, high speed and where a wide temperature range is required.

AR555’s operating temperature range is from – 20˚C to 250˚C. Its properties make it suitable in ‘lubricating for life’ applications.

  • A few of the critical uses of PerFluoroLube® greases include:
  • Vacuum pumps
  • Roller bearings of suspended conveyors in furnaces
  • Mechanical components operating under high load, high speed
  • Nuclear industry lubricants
