Gelsenkirchen, Germany -- Industrial hose maker Norres has developed two patented coupling systems for externally corrugated spiral hoses, the company said in 12 May statement.
The two clamp systems - Norconnect 231 and Norconnect 232 - can be used in conjunction with Norres' Airduc PUR 355 MHF and 356 MHF polyurethane hoses, as well as a number of the German company's other products.
The coupling systems were specifically developed for heavy and super-heavy, externally corrugated spiral hoses, Norres said in the statement. Norconnect 231 is suited for use in the plastics industry while Norconnect 232 is aimed at food, pharmaceutical and chemical applications.
Norres added that the polyurethane used for the sealing insert in Norconnect 231 is food-grade and complies with the regulations of the American Food and Drug Administration and the equivalent European directives.
