Hygienic Usit速 Ring

Hygienic Usit® Ring The Hygienic Usit® Ring is a flat stainless steel washer with on the outside diameter a vulcanized EPDM sealingring for static sealing free of dead-spaces.

The Hygienic Usit® Ring (bonded seal) is specially developed by Freudenberg Process Seals for use in the food and beverage, pharmaceutical and biotechnology industries. This sets new standards for the process industries.

The Hygienic Usit® Ring is a further evolution of the standard Usit® ring and seals flanged bolt heads and dome nuts, according DIN EN 1665. This design of the Hygienic Usit® Ring in combination with the flanged bolt head or dome nut prevents the medium from penetrating under the bolt head or nut what can cause growth and formation of germs and bacteria. The Hygienic Usit® Ring design, which is tailor-made for hexagon bolts with flanges, ensures that the

sealing ring is cleanly seated on the flange, precluding the formation of air spaces where microorganisms can accumulate.

That’s why today’s facilities are predominantly cleaned without disassembly and instead using CIP, WIP and SIP methods.

flanged execution according DIN EN 1665 in stainless steel 316L. This flanged bolt and/or flanged dome nut together with the Hygienic Usit® ring forms an extremely easy-to-clean combination, which has already been tested and approved by the Weihenstephan Research Center for Brewing and Food quality using the “EHEDG Cleanability Method”.

The Hygienic Usit® ring is with that certified

by EHEDG, Type EL-Class I.

Therefor is the Hygienic Usit® Ring your best choice for your hygienic solution!

The 70 EPDM 291, a premium compound for the food and beverage and pharmaceutical industries is FDA, EC1935/2004 approved and has been tested and approved for use in pharmaceutical components and facilities according USP class VI (tot 121°C).

For the bolts and dome nuts has Freudenberg Process Seals chosen for a

NB: only the combination bolt ,nut and Hygienic Usit® ring is conform “EHEDG Cleanability Method”.
