FKM has highly useful thermal properties due to its ability to withstand both high and low temperatures whilst operating normally. It is able to do so far better than many other elastomers, due to its resilient and hard-wearing nature. Combine this with its low-burning characteristics, and you have a popular material for industrial applications.

Hard Wearing

One of FKM other benefits is its resistance to oil and chemicals, and this is not diminished when exposed to high temperatures. In fact, FKM operates normally from -10°C right up to 120°C. The combination of the two make it highly desirable for use where it will come into contact with high or low operating temperatures and corrosive chemicals.

Dealing with the Negatives

One of the only downsides to the use of FKM products is the chance of toxic vapours being given off due to the high temperatures the material is exposed to during industrial use. In these cases protective measures should be taken when handling the FKM material.

FKM Industrial Uses

FKM is widely used in the aerospace and automotive industries amongst others. These are industries in which high temperatures and compression levels are common. The use of FKM seals, gaskets, hoses and diaphragms reduce heat and corrosion problems in many factories and plants. Because of their thermal properties, FKM products are used in drivetrain systems such as:

  • Crankshaft seals
  • Valve stem seals
  • Air intake manifolds
  • Gaskets


They are also used in fuel systems where their thermal and non-corrosive properties make them an ideal fit for the following:

  • Fuel caps and filter seals
  • Fuel hoses
  • Injector O-rings
  • Fuel sender seals
  • Gaskets
  • Pump seals
  • Pump diaphragms
  • Fuel tank tubing and hoses
