New food-safe approval and patented technology

Hose connection systems are subjected to high demands, especially in the pharmaceutical and food industries. Now customers from the pharmaceutical and food industries can combine the thoroughly tested and approved hoses used for their applications, such as the AIRDUC^® PUR 355 MHF and 356 MHF  from the Pre-PUR^® –MHF hose family, with the patented hose coupling system CONNECT 232. A decisive advantage for the industry: Even the polyurethane material used in the seal is food-safe in compliance with the US Food and Drug Administration (FDA 21 CFR 177.2600 and 178.20) and the corresponding European directives (Directive 10/2011).

Food-safe: The patented CONNECT press fitting coupling system 232

The CONNECT press fitting coupling system 232 was designed by the research and development department at NORRES with applications in the food, pharmaceutical and chemical industries in mind. The manufacturer-patented system comprises a stainless steel pressing sleeve and a sealing insert made of special premium-grade polyurethane. Crucial for use in the food and pharmaceutical industries: The connection is leak-proof, easy to clean, and contains no dead spaces. The hose manufacturer also offers the compatible hose types AIRDUC^® PUR 355 MHF and 356 MHF, with and without stainless steel coil. The food hoses from the Pre-PUR^®-MHF product line have been certified by an independent testing laboratory and been found to conform across the board with the latest EU Regulation No. 10/2011. This means that the hoses can be used for significantly more applications in the food industry. In other words: besides just transporting dry foodstuffs, now liquid and acidic substances can also be transported, including foods containing alcohol and fat. In combination with the patented CONNECT press fitting coupling system 232, which is available in two different stainless steel qualities (1.4301 und 1.4404), the pressed fittings are suitable for use in the food and pharmaceutical industries.

Efficient and safe: The combination patented hose coupling system

The stamped batch number, article number and manufacturer's name help users keep track of the recommended maintenance intervals and avoid confusion or delays when ordering spare parts. That means not only easy maintenance and fast replacement, but also increased efficiency and cost savings in the long run. The PrePur^® material used in the polyurethane hoses, such as the AIRDUC^® PUR 355 MHF and the 356 MHF, offers an abrasion resistance that is five times superior to rubber. The matching, patented coupling system is available in diameters ranging from 25 to 100 mm. The connections are compatible with the profile hoses AIRDUC^® 355 and 356, among others.

In addition, the most common coupling and connection solutions, such as dairy, aseptic, tri-clamp threaded connectors, can be joined easily and securely.
