Hygienic Usit® Rings
Freudenberg's Hygienic Usit®, specially developed for the requirements of the food and beverage industry, establishes new purity standards in open and closed production processes. It can completely replace metallic washers, which are not hygienic and should not be used in food and beverage applications. The Hygienic Usit® can be used for open and closed processes to prevent microbial formation under the screw head. The elastomer bead is available in three tested and exclusively approved materials – all suitable for areas that come into contact with the process medium itself:
- 70 EPDM 291 (black) is resistant to numerous media, such as CIP/SIP media, and to high temperatures
- 70 EPDM 253815 (white) includes RFN (Reduced Friction by Nanotechnology) treatment
- 75 Fluoroprene® XP 45 (blue) for applications with fatty or aggressive media and high temperatures. Plus, the material reliably prevents flavor transfer
The Hygienic Usit® ring seal also offers excellent chemical compatibility for applications involving aggressive cleaning processes, high temperatures, and diverse media. For further details, refer to the comprehensive Chemical Resistance Guide.
All materials conform to FDA and 3-A® Sanitary standards and EU (Reg.) 1935/2004. EPDM also has USP Class VI approval. They are resistant to CIP/SIP processes and media.
The connection is available in the dimensions M4, M5, M6, M8, M10, M12 and M16. As an option, we provide you with specially developed NOVOnox hygienic screws with collar and cap nuts from HEINRICH KIPP WERK made of stainless steel and polished to a high gloss.
