Why this hose?
NORPLAST PVC 389 SUPERELASTICO is a versatile thermoplastic hose for water and slurry handling. The corrugated outer cover and PVC spiral provide extreme flexibility — hence the name "superelastico".
It is economical and covers broadly moderate-load applications in agriculture, construction and pool cleaning. For high temperatures or strong chemicals, choose a hose with specific material selection.
Where it is used
In practice 389 SUPERELASTICO is seen in irrigation installations, construction site water and pool cleaning.
The formal product name is NORPLAST PVC 389 SUPERELASTICO. In daily use: "the super-elastic hose" or "389".

Overpressure and underpressure values are recommended operating limits; the product can be subjected to higher loads on request. Bend radius is measured along the inside of the hose bend.

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 hose is used for moderate-load water and slurry applications:
Agricultural, construction and leisure industries use the hose for irrigation, slurry pumping and pool cleaning.
Custom lengths and assemblies
The hose can be cut to length and assembled with couplings, cuffs and threaded fittings through Particulair's custom hose assemblies.
We offer guidance on material choice, coupling system and grounding, so the hose fits correctly into the overall system. If there is any doubt about zone classification or resistance requirements, a short conversation before ordering is well worth the time.
Frequently asked questions
Why "superelastico"?
The corrugated outer cover combined with a PVC spiral (rather than steel) gives the hose extreme flexibility. It can be bent and rolled to compact storage without permanent deformation.
Can the hose be supplied cut to length with couplings?
Yes. NORPLAST PVC 389 SUPERELASTICO can be cut to length and assembled with couplings, cuffs and threaded fittings through Particulair's custom hose assemblies. We provide guidance on coupling system and sealing so the hose fits correctly into the overall installation.
How do I order the hose, and where do you deliver?
The hose is ordered through Particulair (Karlslunde, Denmark). We deliver to Denmark, the EU and selected third countries such as Norway and Switzerland. Standard dimensions can typically be delivered in 1-2 weeks; custom assemblies and larger volumes require slightly longer lead time.
What is the hose's expected service life?
Service life depends on operating conditions: loading, temperature, chemical exposure, UV and mechanical movement. In standard industrial use, expected life is 3-7 years. Aggressive conditions (high temperatures, continuous flexing, chemical vapours) reduce service life. We recommend regular visual inspection for cracks, deformation or discolouration.
How is the hose best stored before use?
Store the hose dry, at room temperature (15-25 °C) and out of direct sunlight. Avoid contact with ozone-generating equipment (welding equipment, engines). If stored on a reel, the bend must be larger than the specified minimum radius to avoid permanent deformation. Proper storage significantly extends shelf life.
What is the minimum bend radius, and what happens if I go below it?
Minimum bend radius is the smallest radius the hose can be bent to without permanent deformation or internal damage. The table above shows specific values for each dimension. Bending the hose below this limit can collapse the wall, kink the spiral or damage the inner coating. The result is reduced flow, increased pressure loss and shorter service life. Always use bend radius as a design constraint in installation.
What is the difference between working pressure and burst pressure?
Working pressure is the pressure the hose is designed to operate at continuously and safely. Burst pressure is where the hose mechanically fails. The safety factor is typically 3:1 (burst is 3× working pressure), but varies by construction. Running the hose close to burst pressure is never safe in practice — there must always be margin for sudden pressure spikes, temperature changes and material ageing. Stay below working pressure in normal operation.
