5-56 + PTFE

Multifunctional service fluid for use in the professional mechanical maintenance.

Contains PTFE for an extended lubrication function under industrial conditions. Performs extremely well when frequent start, stop or alternating movements occur. Displaces moisture and prevents electrical failure. Provides good protection against corrosion. Ultimate penetration capacity for de-blocking threaded connections or clamped metal surfaces. Cleans and protects surfaces contaminated by machining or handling.

Multi-purpose service spray with PTFE.

A multi-purpose penetrating and lubricating product that breaks through rust and corrosion, displaces water and cleans away scale and dirt. The added PTFE improves the lubrication at the first movement of parts that have been blocked and remains the lubrication function over a extended period.

CRC 5-56 with PTFE is based on a paraffinic oil and a multiple organic inhibitor system that prevents rust and corrosion by forming a continuous protection barrier against water and oxygen.




  • Penetrates quickly, even into the finest pores and cracks of the surface.
  • Lubricates and restores smooth action over an extended period.
  • Displaces moisture out of all electrical and ignition systems and makes it possible to start wet engines.
  • Loosens rusted parts and provides a smooth start up of the movement.
  • Stops annoying squeaks.
  • Leaves a thin film that protects metals from corrosion induced by humidity and other corrosive atmospheres.
  • Easy repair by eliminating the need for disassembly.
  • Safe for all metals and alloys.
  • Safe on most painted surfaces, coatings, plastics and rubbers (if in doubt, test prior to use).
  • Aerosols are equipped with the 360° (upside-down) spray valve and extension tube for added convenience.
  • 500 ml aerosol is equipped with the handy 2-spray valve providing the choice between a wide or a concentrated jet.
  • Aerosols are pressurized with non-flammable CO2 propellant, giving an active product content of over 95% (i.e. over 30% more than typical hydrocarbon propelled products).
