Work safety notes

Work safety regarding working with a knife:

  • Always wear cut-resistant gloves
  • Arms must be held in parallel position. Do not cross arms while cutting
  • Hold the hose a minimum safe distance of 10cm from the cutting tool

Grounding for protection against electrostatic charging

Effective and permanent grounding of all installation components (including hoses and hose fittings) provides protection against disruption to media flow or ignition of explosive atmospheres. Please note our corresponding data sheet electrostatic charging.

Variant 1: Expose the spiral, bend it to the inside and insert the conductive hose fitting.

Pulling out the earthing wire of NORPLAST® PUR-C / PVC-C AS hoses

The copper grounding wire is integrated into the hose wall between the hard-plastic reinforcing spirals.

Step 1: Cut half of a circumfer-ence of the hose wall next to the grounding wire. The grounding wire stays on the residual part of the hose.

For grounding, bend the ground-ing wire into the hose and insert the conductive hose fitting to be earthed.
For grounding, bend the ground-ing wire into the hose and insert the conductive hose fitting to be earthed.

Notes on electrical grounding:

  • The grounding wire should be electrically grounded on both ends of the hose.
  • After grounding, measure the electrical resistance between the two grounded hose ends. The electrical and surface resistance should measure <109 Ohm.

Please take into consideration any special regulations, local laws or provisions that are applicable to your situation or application.

Leak-proof assembly

A satisfactory seal can be assured when using our specially-developed spiral hose clamps. Leaking media can pose a threat to people and the environment, as well as causing process problems and reduced efficiency.

NORDUC® one hand assembly system

Due to the conic inside and the snap in hooks, the connector is universal suitable for different tube profiles. (Stand-ard-, Coarse- and UFW-profile) IP 65 is reached acc. to EN 60529/IEC 60529 in this combination. The IP 68 rate is attained with an O-ring sealing, mounted in the first wave trough of the tube (trade size 50 in the first and second groove).

Step 1: Separate the tube at a cor-rugation crest (optimal protection of the tube and connector).
