Sealing washer for Hygienic Usit® screws - Flat metal gasket with elastomer bead for cavity-free, static sealing of screwed connections. - Material: Stainless steel 1.4404 (316L) Rubber seal: 75 Fluoroprene XP 45, blue Advantages - The sealing washer ensures there is no risk of any cavities within a screwed connection. - Residues or cleaning liquids cannot not settle unnoticed thus avoiding any contamination by germs or bacteria Use - Even if, when tightening the screw connection, the elastomer bead cannot be overloaded by the integrated stainless-steel washer, any material will arrive sooner or later at the end of useable life. Fragments could then be found in foodstuffs. The sealing materials used and the colours used make it easy to detect these unwanted elements Applications - For special requirements, such as very greasy and corrosive liquids or very high temperatures, which can occur for example, during cleaning operations
