Food-grade clamp-profile hose in polyurethane. The galvanised steel clamp profile provides high mechanical robustness and eases assembly with couplings. Built for large-scale bulk conveying of food and pharmaceutical products. The dimension range (Ø 50-1000 mm) is broader than most other food hoses, covering everything from smaller food production to large silo unloading systems.

Why this hose?
CP PUR 455 FOOD is specialised for large-scale bulk transport. The clamp profile construction — a galvanised steel band running spirally around the hose — provides mechanical robustness and eases assembly with CP couplings. It is the preferred construction on silos and bulk systems above Ø 200 mm.
The hose is food-grade per EU 10/2011, FDA 21 CFR 177.2600 and GMP. The dimension range (Ø 50-1000 mm) is broader than most other food hoses, covering everything from smaller filling machines to large silo trucks.
Where it is used
In practice 455 FOOD is seen on silos, silo trucks and large bulk systems in food production and feed distribution.
The formal product name is CP PUR 455 FOOD. In daily use: "the clamp-profile food hose" or "CP 455 FOOD".

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 large-scale bulk transport in food and pharma industries:
Food, pharma and agricultural industries use the hose for large-scale bulk transport where the clamp profile construction is necessary due to the large dimensions.
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 a clamp profile?
A clamp profile is a rigid galvanised steel band that runs spirally around the hose to give it its shape. It differs from standard spring-steel spirals by providing higher mechanical robustness and easier assembly with standard CP couplings. For large dimensions (above Ø 200 mm), clamp profile construction is often the only practical option.
Is the hose ATEX-approved?
No. CP PUR 455 FOOD does not have an antistatic wall and is not ATEX-approved. For classified zones with food contact, an AS variant such as AIRDUC® PUR-INOX 351 FOOD-AS (MD) is recommended.
What sizes are available?
Up to Ø 1000 mm in the main variant — markedly larger than most other food hoses. That makes it suitable for large silos and bulk systems where flow is high.
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.
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.
What does "GMP-certified manufacturing process" mean?
GMP (Good Manufacturing Practice) per EU 2023/2006 means the manufacturing of the hose is controlled, documented and traceable from raw material to finished product. It is not only the product that is food-grade — the production process itself is subject to food-safety protocols. This is typically mandatory for pharma and food industries where traceability is a formal requirement.
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.
