The unit reliably seals screw and bolt heads to protect aseptic isolators and areas that make contact with both the product and external influences from the risk of contamination, the manufacturer states. With an external sealing, the Usit washer isolates the space between the bolt and the surface from all external influences to protect the product. The device can also be used for internally vulcanized, trapezoidal and leave air spaces where fluid and product deposits can collect, Process Seals suggests.

The Hygienic Usit’s sealing bead is made of 70 EPDM 291 material, which is compliant with Food and Drug Administration, EC 1935/2004 requirements and is biologically safe according to United States Pharmacopoeia Class VI criteria up to 121°C, making it the ideal choice for hygienically demanding applications in the process industry. Additionally, the washer is specially constructed for use with hexagon bolts with flanges (DIN EN 1665) and is available in the standard sizes M5, M6, M8, M10, M12 and M16.
