Why this hose?
RADIACORD®/DIN is a specific cooling water hose certified per DIN 73411 — the German standard for radiator hoses and cooling tank hoses. The EPDM construction is chosen for compatibility with antifreeze agents (glycol-based) and high temperature tolerance up to +130 °C.
The application range is classic: engine cooling in vehicles, industrial cooling systems and heat transfer in process industry. For aqueous applications without antifreeze or at higher temperatures, other hoses in the range are available.
Where it is used
In practice RADIACORD®/DIN is seen on engine cooling, industrial cooling systems and cooling water circuits.
The formal product name is RADIACORD®/DIN. In daily use: "the radiator hose" or "the DIN cooling hose".

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 cooling water applications:
Automotive, energy and machine industries use the hose as a standard cooling water and antifreeze hose.
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
Which antifreeze agents does the hose tolerate?
The EPDM construction is compatible with standard glycol-based antifreeze agents (ethylene glycol, propylene glycol). Consult the manufacturer's chemical resistance table for specific chemicals.
Can the hose be supplied cut to length with couplings?
Yes. RADIACORD®/DIN 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.
Which chemicals is the hose resistant to?
Specific chemical resistance depends on material selection, concentration and temperature. The manufacturer maintains an extensive chemical resistance table showing compatibility for hundreds of chemicals. It can be downloaded from the Documentation section above. If in doubt about a specific chemical or mixture, contact Particulair — we can advise based on your concrete process.
Does temperature affect the hose's chemical resistance?
Yes, significantly. Higher temperatures accelerate chemical attack and reduce the material's resistance. A hose fully compatible with a chemical at 20 °C may be underrated at 60 °C. The manufacturer's chemical resistance table typically lists values at 20 °C; at higher operating temperatures, compatibility must be reassessed. We always recommend a consultation before choosing a hose for chemical transport at elevated temperatures.
