Installation sketch USIT-Ring

USIT rings are used for industrial applications in which high seal tightness is required, high pressure predominates and a secure sealing effect must be guaranteed, for example, in the processing, food or pharmaceutical industries. The USIT rings of Freudenberg Sealing Technologies are metallic flat seals with an internally or externally vulcanised, trapezoidal, rubber-elastic sealing bead for the static sealing of screw and flange connections. The sealing bead guarantees a safe, self-reinforcing sealing effect.

USIT-rings from Freudenberg Sealing Technologies: Secure sealing

USIT-rings from Freudenberg Sealing Technologies are metallic flat seals with an internally or externally vulcanised, trapezoidal, rubber-elastic sealing bead for the static sealing of screwed and flanged connections. They are used primarily in the processing industry as well as in the food and pharmaceutical sectors. USIT-rings are used wherever high seal tightness is required, there are high pressure levels present and secure sealing must be ensured. The USIT-rings from Freudenberg Sealing Technologies are characterised by their high performance as well as simple installation whilst still providing maximum seal tightness. The sealing bead of the USIT-rings provides a secure, self-reinforcing seal even under the most challenging conditions such as high pressure levels.

USIT-rings in a hygiene-compliant design

Especially for the challenging needs of the processing industry, Freudenberg Sealing Technologies has developed the USIT-Ring Hygienic USIT®. In contrast to standard USIT-rings, these are EHEDG-compliant and ensure that no germs or biofilms can form as bacterial colonies or corrosion under the bolt head. This ensures a hygienically optimised design. The metallic flat seals facilitate an extremely reliable seal free of dead space. For applications with particularly aggressive CIP/SIP cleaning and high steam sterilisation temperatures as well as process media with a fat content, Freudenberg Sealing Technologies utilises the fluorinated premium compound Fluoroprene® XP 45 material. This means the V-Ring can be used even at even higher temperatures and in addition, is resistant to polar and non-polar media and to aroma substances.
