General description

Quick acting penetrating and lubricating oilt A no compromise penetrating product that attacks rust and corrosion, penetrating through oxides and soil to free corroded fasteners and mechanical components Its low surface tension formulation quickly disperses rust, scale and corrosion, aiding disassembly of close tolerance fasteners and assemblies Penetrating Oil + M052 is based on a refined paraffinic oil, inhibitors and contains MOS] solid lubricant for reduced wear.


  • Penetrates into hard-to-reach areas quickly.
  • Disperses rust, scale and other oxides.
  • Frees metal parts seized by dirt, rust, corrosion or dried-up greasy deposis.
  • Eases quick disassembly of mechanical components, fittings, assemblies, nus and bolts and omer close tolerance fasteners.
  • Leaves a solid lubricating M052 film.
  • Reduces wear and facilitates future disassembly.
  • Lowers maintenance costs.
  • Reduces scrap rate of seized parts.
  • Does not contain silicones.
  • Safe for all metals and for most plastics and rubbers (if in doubt, on-the-job testing prior to use is advised).
  • Aerosols are equipped widw the 360° (upside-down) spray valve and extension tube for added convenience.
  • Aerosols are pressurized with non-flammable C02 propellant, giving an active product content of over 95%.
  • Specifications: –
    • meets the requiremens of W-P—Zle.
    • NSN 9|50-I3-I I3-734I.


  • Seized and rusted nuts and bolts
  • Locks and hinges·
  • Screwed parts·
  • Equipment disassembly·
  • Corroded fasteners·
  • Valves·
  • Air tools·
  • Chains and conveyors·
  • Agricultural equipment


  • Apply liberally, saturating problem areas. Use extension tube for hard-to-reach areas.
  • Allow a few minutes for penetration; tap joint ligifly to aid penetration.
  • Repeat if necessary for stubborn joins, fasteners and assemblies.
  • If necessary, to be removed by CRC Fast Dry Degreaser or CRC Industrial Degreaser. A safety data sheet (MSDS) according EU directive 93H l2 is available for all CRC products.
