How is the antistatic hose constructed?
An antistatic hose is constructed in two ways, depending on its intended use. We distinguish between transfer hoses and extraction hoses.
Antistatic transfer hoses
Transfer hoses are used to pump a medium under pressure, so their construction usually consists of three layers:
- inner,
- middle (or reinforcement),
- outer.
The inner layer is characterised by its abrasion resistance and smoothness, which facilitates the transport of solid and semi-liquid media (and also prevents their deposition). The outer layer, on the other hand, provides the hose with adequate mechanical strength and insensitivity to the environmental conditions in which it will operate.
What materials are antistatic hoses made of?
The most common material for antistatic hoses is plastic (PVC, PU, etc.) and rubber compounds (NR, SBR, EPDM, etc.).
How is the reinforcement of the antistatic hose built?
As for the reinforcement of the antistatic hose, it takes the form of a synthetic or textile braid/cord. It is thanks to this that the hose can withstand higher working pressures.
Antistatic extraction hoses
The design of antistatic extraction hoses is usually simpler. In the standard version, they have only one layer of material (usually PU/PE plastic) and reinforcement in the form of a steel wire spiral or hard PVC.
It is precisely because of the latter that they are vacuum-resistant, i.e. they allow the medium to be sucked in.
What makes an antistatic hose anti-static?
Hose antistaticity is achieved in two ways:
- through the use of copper wire - the copper wire present in the hose construction ensures electrical continuity so that charges do not collect inside or on the surface of the hose;
- through material admixtures - these ensure that the natural insulator conducts charges in a controlled and slower way, so they will never be strong enough to cause ignition.
Rubber compounds or plastic are used for the production of an antistatic hose. Both of these materials are insulators, meaning that electrical charges cannot move freely in them.
Air also has the characteristics of an insulator, so the same problem exists with pneumatic transport.
It is worth adding here that, in the case of copper wire, it must be continuously connected In addition, experts recommend regular inspection of such an installation. A line is no substitute for an antistatic inner layer.
What's more, when you need a hose for work in an explosive atmospheric zone (ATEX), carry out a proper risk check.

FAQ
Do I need an antistatic hose?
Yes, you need an antistatic hose if you are transporting a medium that creates static electricity through friction (e.g. substances with particles). It will help you avoid unnecessary costs and risks associated with using equipment that is not suitable for static electricity. Potential risks include clogging of the hose due to the accumulation of an electrified substance, as well as the possibility of causing a spark that leads to a fire or (worse) an explosion.
What are the advantages of antistatic hoses?
Among the advantages of antistatic hoses are increased safety at the workplace, good resistance to friction and other environmental conditions (depending on the type of hose), a smooth inner layer (which makes it easier to transport the medium and prevents it from settling), and a wide range of varieties of this type of product.
From what materials are antistatic hoses made?
Antistatic hoses are made of various materials, but primarily plastics (PVC, PU, PE, PTFE) and rubber compounds (NR, SBR, EPDM). Although in both cases we are dealing with insulators, they acquire antistatic properties thanks to suitable additives.
