Help with material selection
Even though this hose is not 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:
Industries that use it
The manufacturer lists, among others:
Construction, municipal technology and municipal vehicles, plastics industry, the cleaning industry and silo and conveying technology.
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
What is the difference between PUR 387 and PUR 387 AS?
PUR 387 is the version without the antistatic property. The manufacturer states no electrical resistance for it, so it must not be used for combustible dust. If the hose is for combustible dust, look at NORPLAST® PUR 387 ANTIABRASIVO® AS.
