Höfert Italia has specialised in the production of O-ring seals and technical items. The standard dimensional tolerances for the O-rings are given in the standard ISO 3601-1. As concerns the technical items, the tolerances generally applied are ISO 3302-1 (ex DIN 7715 M2) or those required upon Customer’s drawing. The different production stages are constantly monitored according to an accurate control plan based on real-time technology. From the acceptance of raw materials to the final packaging of the items, our production cycle – methodically controlled by making use of high precision equipment – allows us to obtain a product with an excellent quality/price ratio.


Main target of the company Höfert Italia S.p.A. is the steady development of its production process, by taking advantage from the best technologies available to ensure a top quality product to the Clientele. Besides, our organisational flexibility allows us to meet the manyfold requirements of our Customers, thus reducing the downtimes.




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. The O-ring sizes range from 0.50 to 1025.00 mm of internal diameter and from 0.50 to 20.00 mm of cord thickness. Download the format Excel file to get our updated range of moulds.
