Why this hose?
MILKCORD®/SP is specialised for milk and dairy products. The practical detail is the combination of three properties: NBR inner tube that resists lactic acid and fat, mirror-smooth interior that minimises deposits and eases cleaning, and steam-cleanable wall at 130 °C for up to 30 minutes — critical for CIP protocols in modern dairies.
The hose is certified per EU 1935/2004, FDA 21 CFR 177.2600, the German BfR XXI:2002 (Cat. 2) and GMP. That covers both EU and US food regulation for dairy contact materials.
Where it is used
In practice MILKCORD®/SP is seen at dairies as a connection hose between milk tank and processing, and on milking systems for direct milk extraction from cows.
The formal product name is MILKCORD®/SP. In daily use: "the milk hose".

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 dairy and food industries:
Dairy and food industries use the hose for milk handling and dairy products, from direct milk extraction on milking systems to connection hoses in pasteurisation plants.
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
Can the hose be steam-cleaned?
Yes. The hose tolerates steam cleaning at up to 130 °C for up to 30 minutes (without pressure). This is specifically designed for daily CIP cleaning in dairies where sterilising steam is part of the hygiene protocol.
Why NBR instead of PUR?
NBR (nitrile rubber) has a specific chemical resistance that suits milk and dairy products well, including lactic acid and fatty dairy fractions. PUR is better for dry foods and powders, while NBR is the right choice for liquid dairy media.
Does the hose tolerate alcoholic dairy products?
Yes, up to 15% alcohol content. That covers cream-based liqueurs, kefir and similar.
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.
