Food hoses are intended to come into contact with food products and semi-processed food products. They are made from materials approved to come into contact with food. Their inner layer is made of rubber compounds, which are white, odour-free and taste-free but also of PVC, polyethylene and other polymers that feature high level of purity, do not contain harmful additives (plasticisers, fillers, stabilisers, colourants etc.) deteriorating organoleptic characteristics of transferred products. Depending on their type, the hoses are suitable for such foodstuffs as, for example: drinking water, milk and dairy products, alcohol, fruit juices, beverages, fats, oils etc. These hoses can be also used in the pharmaceutical and cosmetics industry.

Drinking water hoses – requirements
Drinking water or potable water, that is water intended for human consumption, is defined as: water in its original state or after treatment, intended for drinking, cooking, food preparation or other domestic purposes, distributed through a water supply network, supplied by water tankers, in containers or bottles, and all water used in food production.
Water and water supply systems are subject to special legislation – general European legislation (Directive 98/83/EC) and detailed requirements of a state hygiene institute respective for a country, where the water hose will be used. The National Institute of Hygiene (PZH) assures water safety in Poland. The State Sanitary Inspection supervises the use of materials and articles for potable water. In Germany, plastic materials and articles that are in contact with drinking water should meet the requirements of KTW and DVGW. WRAS approval is to show the conformance with regulations in Great Britain, whereas in the USA it is NSF-61. These certificates are granted by country-specific institutes but are accepted and recognised in many countries.
Safe water (drinking water/potable water) is defined as water intended for human consumption:
Flexible delivery hose designed to convey cold drinking water (+23°C) and hot drinking water (+60°C).
The white, mirror-smooth inner surface:
The external layer is resistant to abrasion, ozone and atmospheric conditions. A suction-delivery hose version with a steel helix is available on request.
Standards and requirements:
Assembly of fittings to hoses.
Fittings for food hoses are mounted with worm drive clamps or ear clamps, they can also be crimped with ferrules. The food hoses basically come with AISI 316 stainless steel fittings. Their inner surface must have perfectly smooth finish of hygienic quality.

The hose (with or without fittings) can be detached from the installation and cleaned separately, by rinsing, using detergents and disinfectants, and if necessary, sterilisation. Apart from the methods above, a procedure of cleaning the whole installation without dismantling is used in the food industry:
