Help with material selection
Although this hose isn't ATEX-relevant, these two articles provide useful background on electrical resistance and industrial safety — important if you later combine the hose with electrical equipment or work in mixed environments:
The invisible weakest link
Why a conductive or antistatic hose isn't sufficient on its own — and what grounding means for the complete system.
Know your ohm
The difference between antistatic and conductive, which resistance limits apply where, and how to measure them correctly.
Industries that use it
The hose is used in:
Agriculture and vacuum handling systems.
Custom lengths and assemblies
The hose can be cut to length and assembled with couplings. We advise on the assembly so the hose fits your installation.
Frequently asked questions
Which working pressure does the hose withstand?
The manufacturer's data sheet states vacuum for each size but no working pressure. Ask us and we will clarify it for your application.
