Why this hose?
EVA 373 is constructed for a specific application where material and temperature capacity must match the requirement. EVA (ethylene-vinyl-acetate) is chosen because it provides the right balance between flexibility, chemical resistance and temperature capacity.
Continuous industrial operation subjects the hose to daily pressure cycles, mechanical wear and temperature variation. The difference to a standard hose lies in the material's formulation and the reinforcement's dimensioning.
In daily use, the hose's life cycle is 5-10 years depending on load. Preventive maintenance with annual inspection extends the service life.
Where it is used
EVA 373 is typically used in industrial contexts where a standard hose cannot handle the load. Specific application depends on the variant - see intro for details.
The hose is typically mounted between a source and a destination via metal or polymer couplings. We advise on sizing and couplings.
Industrial installation often requires pressure testing at commissioning and annually thereafter. This is documented in the installation history.
EVA is colloquially known as a suction hose or vacuum cleaner hose.

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:

Industries that use it
The EVA series is highly flexible suction hoses for industrial vacuum cleaners, floor cleaning machines and other suction applications.
The EVA material (ethylene-vinyl-acetate) combines high flexibility with reasonable chemical resistance. It is the European standard material for industrial suction applications where PVC does not have sufficient resistance.
The hose is crush-resistant - it recovers its shape after compression and can lie under feet without permanent damage. This is critical in mobile cleaning systems where the operator moves freely.
The EC variant has added conductivity (wall resistance below 10^6 Ohm) for ATEX applications where static electricity is a risk - typically for suction of dust or combustible solvents.
Custom lengths and assemblies
The hose can be delivered cut to desired lengths. The standard roll lengths can be supplemented with shorter pieces or continuous rolls by arrangement.

Frequently asked questions
What is the difference between EVA 373 and EVA 373 EC?
EVA 373 is the standard suction hose, insulating. EVA 373 EC is the conductive variant with wall resistance below 10^6 Ohm, making it ATEX-suitable for applications where static electricity is a risk (dust suction, combustible solvents).
Which machines does EVA 373 fit?
Typically industrial vacuum cleaners, floor cleaning machines, pool cleaning robots and mobile suction machines. The hose is connected via standard hose connections found on most cleaning systems.
Is EVA 373 chemically resistant?
Yes - the EVA material is resistant to typical cleaning agents, water, diluted acids and bases, and common solvents. Check the resistance table for the specific chemical or contact us.
Can EVA 373 EC be used in all ATEX zones?
The EC variant is typically approved for zones 21 and 22 (dust) and zones 1 and 2 (gas) - check the specific factsheet for the product. The hose must be properly earthed to function conductively.
How long does EVA 373 last?
Service life depends on load and particle aggressiveness. In daily professional use, 3-7 years is typical. The hose must be replaced at visible cracks or kinks.
What temperature does EVA 373 withstand?
The hose is intended for -20 to +65 C. It is not suitable for hot media above 65 C - for higher temperatures, a silicone or neoprene hose should be selected.
Can the hose be delivered in other lengths?
Yes - the standard roll lengths can be supplemented with shorter pieces or continuous rolls by arrangement. Standard connections for most suction systems can be supplied with.
How do I store the hose?
Store dry at room temperature, protected from direct UV light. The hose can be rolled up without damage. Washing of the hose is possible - use standard cleaning agents and let the hose dry completely before storage.
