Hygienic Usit® 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
