Bellows, Diaphragms, Shaft seals, Gaskets, Pressure seals and Sprays

by JO - Oberrecht GmbH

Logo of JO Oberrecht GmbH


Seals, Bellows or Diaphragms used in the beverage and food industries have traditionally been made from rubber elastomers such as EPDM, NBR or FKM. The now prevailing conditions with regard to static or dynamic stress, temperature, pressure, dry running and the concentration of the media used require materials that take these changes into account. In addition, these products are increasingly used in aseptic environment. Years ago we started to meet these special requirements by building a standard range of PTFE and PTFE grade compounds in JO® quality, that easily can be used in the most common machines, e.g. in the beverage industry.
