With the advanced development of the 17B series, which have been presented on the Achema 2018 for the first time, Eisele has further optimized the sealing system of the successful INOXLINE push-in fittings. In the new design, the O-ring is installed in front of the collet. This improves the tightness of the connection and eliminates gaps in the tube at the sealing point. In combination with FDA-compliant Viton seals, the 17B series is recommended for diverse applications in processing and packaging technology, as well as for use in food and pharmaceutical environment.
