Everything you need to know about silicone hoses

With more than 30 years of experience behind us, we know everything there is to know about the use of silicone hoses in the process industry – and that's quite a lot! In addition, we have built up a large and varied product range that meets the needs of our customers, whether they are involved in food, medicine or chemical production. We carefully select our products and always prioritise quality – especially when it comes to our food-approved silicone hoses.  

In this guide, we will not only teach you about silicone hoses, but also what factors you should consider when choosing your next hose model in this category. Perhaps you produce spirits with a high alcohol content? Or does your production take place in a laboratory or clean room, where hygiene standards are very high? Don't worry – our silicone hoses for foodstuffs cover a wide range of applications and meet all hygiene and quality liners.

Silicone - a unique material for demanding production environments

Silicone is a synthetic material that combines flexibility, durability and chemical stability. In the process industry, it is particularly valued for its ability to withstand extreme temperatures – both hot and cold – without becoming stiff or losing its shape. That is why temperature-resistant silicone hoses are a popular choice among our customers.  

In addition, silicone is biologically inert and does not react with liquids or release harmful substances. The material inhibits bacterial growth and is easy to clean, making it ideal for production environments where hygiene and product integrity are paramount – such as in food production, where food-approved silicone hoses are a liner.  

Silicone can also withstand UV radiation, ozone and a wide range of chemicals, making it ideal in many industrial contexts. Many of our silicone hoses for food last for years – even in harsh, chemical-heavy environments. 

Silicone hoses in the process industry 

Due to the unique properties of the material, silicone hoses are widely used in the process industry. They are particularly popular in pharmaceutical and food production, where high hygiene and consumer safety are crucial. In laboratories and clean rooms, temperature-resistant silicone hoses are used, for example, to transport liquids without risk of contamination, while in the food industry they ensure clean and safe transfer of ingredients without affecting taste or quality.  

In addition, silicone hoses are resistant to repeated cleaning with steam and chemicals – a property that makes them ideal for production environments with strict hygiene requirements. Their high flexibility and wear resistance also ensure that they can handle both low and high pressure without losing their shape or function. 

hoosing the right hose requires a thorough assessment of several factors. First and foremost, you must take into account the temperature and pressure of the medium. If the hose is to transport hot liquids or steam, you should choose a temperature-resistant silicone hose that can withstand even high temperatures without losing its flexibility.  

Another important factor is chemical compatibility. Our range includes solutions for food, chemical and pharmaceutical production, and our food-approved silicone hoses are manufactured to meet all applicable standards for contact with food.  

You should also consider the hose's flexibility and Shore hardness, which must be suitable for your specific application. For example, if the hose needs to be bent frequently, it is important to choose a flexible model – such as one of our silicone hoses for food, which are easy to install and maintain. 

All silicone hoses from our warehouse are ozone and weather resistant, resistant to both ultraviolet light and static electricity, and designed for taste- and odor-free transport of media - properties that make them especially suitable for food and pharmaceutical production. They cover a wide temperature range from as low as -60°C and as high as +200°C, depending on the media. The silicone hoses can also be sterilized via air or steam up to +200°C.

Clearway-SD Platinum premium hose

Clearway-SD Platinum is our premium silicone hose for the most demanding applications and can transport media with alcohol percentages up to 96% without affecting taste or smell. The construction makes it extra strong with a burst pressure of 10 bars. The platinum-cured silicone with a high-gloss finish ensures a smooth, ozone- and weather-resistant surface that is highly hygienic. The built-in stainless-steel spiral and polyester reinforcement provide high flexibility and durability, making Clearway-SD Platinum ideal for confined spaces and demanding production environments. The hose withstands temperatures from -60°C to +200°C and steam sterilization at +135°C. It meets standards such as EC 1935/2004, FDA and USP Class VI for maximum safety and quality.

Platinum Cleanroom: High quality for high hygiene requirements

The Platinum Cleanroom silicone hose is specially developed for the pharmaceutical industry where cleanliness and safety are essential. It is packaged in an ISO 7 certified cleanroom and delivered in double packaging to ensure maximum hygiene from production to use. The platinum-cured silicone with a smooth inner surface prevents particle build-up and ensures optimal flow. The hose is extremely flexible and can withstand temperatures from -40°C to +200°C, making it suitable for demanding process conditions. With approvals such as FDA Title 21 CFR 177.2600, USP Class VI and ISO 10993, it meets the highest standards for medical and biotech applications.

Smooth and FDA-approved silicone hose for laboratory use

Our smooth and FDA-approved silicone hoses, which are especially ideal for laboratory use, are available in both platinum and peroxide cured versions with or without reinforcements. In addition, we also offer a variant with built-in synthetic fabric for extra reinforcement. The common denominator is that they’re all extremely flexible and very user-friendly. They’re also available in different hardnesses measured on the Shore Durometer (Shore Hardness Scale). For example, our peroxide-cured silicone hose without reinforcements comes with a hardness of Shore 60, while our peroxide-cured silicone hose for peristaltic pump has a hardness of Shore 55. The temperature range of these models goes from -40°C to +200°C and both are autoclavable.

Silicone hoses are suitable for transporting liquids with both high and low temperatures. They’re also good for liquids with high alcohol content. In addition, silicone is a durable material that’s stable to a wide range of chemicals.

This means that the silicone hoses meet the strict requirements set by the US Food and Drug Administration (FDA) and are therefore suitable for use in food and pharmaceutical production.

The Shore Durometer (or Shore Hardness Scale) is a measurement of the hardness of certain materials. For silicone hoses, it’s used to determine the flexibility and strength of the hose.

Silicone is stable to many chemicals, making silicone tubing ideal for laboratories, pharmaceutical production and the cosmetics industry.
