NORCONNECT 231 232 NORCONNECT 231 / NORCONNECT 232
The two patented clamp systems were specifically developed for heavy and super-heavy, externally corrugated spiral hoses. NORCONNECT 231 is ideally suited for use in the plastics industry, while NORCONNECT 232 is predestined for food, pharmaceutical and chemical applications.

Polyurethane (PUR) – simply better.

Compared with many other plastic hoses, NORRES polyurethane hoses (PUR) have the following distinguishing characteristics:
  • Less wear (about 2.5 to 5 times better than rubber and about 3 to 4 times better than many soft PVC, see chapt. 14.8)
    → better service life in pumping processes
  • Light and flexible (compared with many rubber hoses, NORRES polyurethane hoses are generally of lower weight and greater flexibility)
  • It is possible to observe the pumping and transport process with transparent and partially-coloured (see Section 0.2) hoses (rubber hoses are usually black and opaque)
    → visual inspection of the pumping and transport process
    → greater operational reliability
  • Excellent mechanical strength – PUR is superior to most other thermoplastic materials in the following ways:
    → very high tensile strength
    → very high elasticity
    → good resilience and low compression set
    → high resistance to tear propagation
  • Good chemical resistance (see chapt. 14.1)
  • Good resistance to UV and weathering (see chapt. 14.8)
  • High softening points and slow heat aging
    → greater residual strength at high temperatures
    → high compression strength
    → greater safety due to material stability
  • Very good flexibility at low temperatures
    → lower "bending force“ at low temperature
    → lower risk of bending fracture at low temperatures
  • Advantageous fire behaviour (in contrast to PVC for example)
  • Generally good environmental compatibility
But polyurethanes are not all the same! For many of its hoses, NORRES uses special ester-polyurethane and ether-polyurethane mixtures that we distinguish with the name Pre-PUR. For more information, please refer to the details on our particularly high-quality Pre-PUR polyurethanes (see chapt. 0.3) and the technical appendix (see chapt. 14.8).
