Samma Parts oil seals keep fluids inside the cylinder and, at the same time, protect against the intrusion of external elements.

The WAS type is available with a protective lip that acts as a dust cover.

It withstands a wide temperature range from -40 °C to +100 °C.

NBR rubber is used in many different fields:

  • Automotive industry
  • Mechanical engineering industry
  • Aeronautical industry
