75 Fluoroprene XP 45 blue
Note:
Flat metallic seal with elastomer beading for cavity-free, static sealing of screw connections. The Hygienic USIT® sealing and shim washer forms a cavity-free seal on product contact surfaces or within aseptic isolators only when used in conjunction with the specially designed screw or nut (see Art. No. K1327 and K1328). The sealing and shim washer reliably eliminates cavities on screw connections. Residual material or cleaning agents cannot precipitate unnoticed and so contamination through microbes and bacteria is negated.
