Vario Couplings, Bohlender

2-part coupling for connecting elastic tubing such as Silikon®, Viton®, Tygon® etc. with non-elastic tubing made of glass, metal, PTFE or other plastics. Functioning is as easy as it is ingenious. The elastic tubing is pushed on a cone and fixed on the actual coupling by means of a sleeve nut. A variety of threads are available for connecting at the other end of the non-elastic lines. Ideally suited for use with tube pumps.
