WARNINGS

Various external factors may affect the physical and mechanical characteristics of the O-rings throughout their storage. Comply with the following recommendations in order to guarantee their good state of preservation.

  • Avoid the exposure to radiation and to weather.
  • The packaging bags shall be properly arranged on the shelves in order to avoid any distortion or deformation of the O-rings which, with the time, may become permanent.
  • The O-rings must be stored at room temperature
  • The storage places shall be dry and well ventilated in order to avoid the presence of moisture over a long time.

Our production department has approximately 4,000 moulds available to obtain as many dimensions of O-rings (3,400 injection moulds – 600 compression moulds) and approximately 500 moulds for shaped items upon Customer’s drawing.
