Why this hose?
CP PTFE-INOX 475 FOOD is the definitive hose for pharma and demanding food processes. PTFE (polytetrafluoroethylene, commercially known as Teflon®) is chemically impermeable — resistant to practically all industrial chemicals. Combined with stainless steel clamp profile, it produces a hose that handles both the most aggressive media and high temperatures.
Food approval is at the top level: FDA 21 CFR 177.1550 (PTFE-specific), EU 10/2011 + EC 1935/2004 and German BfR XV. For pharma with active ingredients or food production with chemical vapours, it is the top choice.
Where it is used
In practice CP PTFE-INOX 475 FOOD is seen in pharmaceutical production with active ingredients, food factories with chemical vapours and vapour return systems at higher temperatures.
The formal product name is CP PTFE-INOX 475 FOOD. In daily use: "the PTFE food hose" or "475 FOOD".

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 in the most demanding pharma and food processes:
Pharmaceutical, food and chemical industries use the hose for processes where PTFE's chemical resistance combined with food approval is critical.
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
What is the difference between PTFE-INOX 475 FOOD and 475 EC?
Both have PTFE wall and INOX clamp. The EC variant is electrically conductive (<10⁶ Ω) and ATEX-approved; the FOOD variant is not conductive but is food-grade per FDA 21 CFR 177.1550 and EU 10/2011. Choose FOOD for pharma and food; choose EC for classified chemical zones.
Does it really tolerate all chemicals?
PTFE is practically chemically inert — it resists all standard acids, bases, solvents and food media at temperatures up to +250 °C. For specific extreme media, consult the manufacturer's chemical resistance table.
Can the hose be supplied cut to length with couplings?
Yes. CP PTFE-INOX 475 FOOD 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 do EU 10/2011 and EU 1935/2004 mean?
EU 1935/2004 is the framework regulation for materials and articles in contact with food — the overarching safety baseline. EU 10/2011 specifies plastics materials in food contact, including migration limits and test categories (A=aqueous, B=acidic, C=alcoholic, D=fatty, E=dry). When the hose is tested for relevant categories, it means it is safe for food contact with those media types.
