Oil Seals & O-Rings

Rotary Shaft Seals

Rotary Shaft Seals are available from stock in NBR and FPM compound. They are produced in single or double lip, with covered or uncovered metal parts, with reinforced textile rubber or reinforced metal case, as well as in many other different profiles.

Front Seals and V-Rings

The fully elastomer axial seal, V-ring, which is mounted directly on the shaft is a very popular product thanks to its high quality and versatility. The full range of standard profiles is available in NBR and FPM. Any other compound can be supplied upon request.

Wiper Seals

This product is used to protect seals from dirt during reciprocating motions. Wiper seals are available in three different combinations: rubber only, rubber covered insert and with outer metal housing.

Hydraulic Seals

These packing seals are composed of lip rings made of a cotton fabric reinforced elastomeric compound and are suitable for reciprocating movements. They can be fitted on cylinders as well as on pistons in a variety of applications from light duty to the heaviest working conditions.


O-rings are the most common sealing product used in static or dynamic applications. Our O-rings are available in molded, hot vulcanized or with a teflon encapsulation enclosing a core of Silicone or Viton elastomer.


Nitrile Rubber (NBR)

Standard colour: black.


  • Good resistance to mineral oil and grease
  • Good resistance to water and radiator fluid


  • Poor resistance to high-alloyed hypoid oil
  • Poor resistance to ozone, weathering and sunlight
  • Not resistant to automotive brake fluid (glycol based)
  • Poor resistance to polar fluids (ketones, ethers, esters)
  • Poor resistance to chlorinated hydrocarbons (carbon tetrachloride, trichloroethylene)
  • Poor resistance to aromatic solvents

Fluorinated Rubber (FPM)

Standard colour: brown


  • Excellent resistance to mineral oil and above all high-alloyed hypoid oils
  • Excellent acid resistance
  • Good resistance to aromatic and chlorinated hydrocarbons
  • Excellent resistance to ageing, ozone and weathering


  • Limited cold flexibility
  • Poor resistance to polar fluids (ketones, ethers, esters)

Silicone Rubber

Standard colour: red


  • Retains flexibility down to very low temperatures
  • Withstands continuous heating at high temperatures without hardening
  • Resistant to mineral oil and greases
  • Excellent resistance to ageing, weathering and ozone
  • Good chemical resistance to alkalis


  • Not recommended for use with hydrocarbons such as petrol and paraffin, and lighter mineral oil or steam over 3.5 bar
  • Not resistant to hot water, acids and non-mineral automotive brake fluids
