Hoses for Hot Water and Hot Chemicals
With over 40 years of expertise in hose & tube technology, Reichelt Chemietechnik is your partner for professional, high-quality hot-water hoses and many other laboratory and industrial hose lines. When transporting hot water, hot chemicals, or other heated media, conventional chemical hoses are often insufficient. Our range, available to order directly in our online shop, includes a wide selection of hot-media tubes made from different materials for use in process engineering, chemical processing, and chemical technology. Even physiologically safe designs that comply with FDA, BfR, and USP Class VI regulations can be obtained quickly at the click of a mouse.
Which materials are available for hot-water hoses?
- Butyl (butyl rubber, Butyl-IIR)
- EPDM (ethylene-propylene-diene rubber)
- SBR (styrene-butadiene rubber, Buna®)
- Silicone (silicone rubber)
- NBR (acrylonitrile-butadiene rubber, Perbunan®)
- PVC (polyvinyl chloride)
The right material for your application depends on the respective operating conditions.
The right hot-water hose for your application
Since the selection of a suitable hot-water hose depends on your process conditions, you should consider the following questions before choosing:
- What pressure and temperature loads will the hose be exposed to?
- Which media need to be conveyed?
- Is translucency or transparency of the material relevant?
- Is a flexible and elastic design necessary?
- Which bending radii must be achieved?
- Which nominal diameter is required for optimal flow?
Once these parameters are defined, the material overview will quickly guide you to the correct solution for your specific application.
Hot-water hoses available in 1/4 inch, 1/2 inch, and 1 inch
The 1/4 inch hot-water hose corresponds to approx. 6.35 mm and is available in smaller variants with an inner Ø of 9.5 mm (article 498980-13802). The 1/2 inch (12.7 mm) hot-water hose covers the medium size range with an inner Ø of 12.7–19 mm (articles 13803-13812), while the 1 inch (25.4 mm) version corresponds to the larger designs with an inner Ø of 25.4 mm (articles 13813-13814). In addition, we also supply tubes from 0.8 mm inner diameter up to 40 mm – both below 1/4 inch and above 1 inch.
The wall thicknesses vary between 1.6 mm and 4.8 mm, which directly affects pressure resistance. The hoses are available in lengths of 5 m and 10 m.
The different hot-water hoses and their advantages
The specific properties and advantages of the materials and the resulting water hoses will be explained in the following text.
Butyl rubber hot-water hose
Butyl hoses are made of butyl rubber, an elastomer with very low gas permeability. They are therefore primarily used for gases but also serve for water and hot-water applications. The permissible temperature range is –30 °C to +140 °C (short-term up to +140 °C). The Shore hardness of these rubber-elastic products is 60°.
PVC hot-water hose
Polyvinyl chloride is not inherently highly temperature-resistant. However, PVC chemical pressure and spiral types – two special variants of this polymer, optionally reinforced with braided fabric inserts – are still suitable for hot water, hot media, and oils (e.g. heating oil). Under these conditions, they are largely resistant and also sterilizable, flame-retardant, robust, and pressure-resistant. The pressure resistance of these cost-effective hoses reaches up to 24 bar at +20 °C (depending on dimension). The material is flexible, durable, aging-resistant, and abrasion-resistant – providing a reliable and economical all-round solution adequate for many applications.
EPDM hot-water hose
EPDM is a particularly soft, flexible, and elastic polymer, ideally suited for hot-water applications. These tubes can generally be used in a temperature range of approx. –40 °C to +120 °C, with saturated steam conveyable up to +210 °C. To withstand extreme steam and water pressure, the rubber hoses are often reinforced with an additional outer jacket, integrated polyester fabric, or a steel wire braid.
For especially demanding operating conditions, Reichelt Chemietechnik manufactures EPDM special hoses suitable for hot media, hot water, and other hot chemicals. These high-temperature pressure hoses can handle operating pressures of up to 6 bar and are available in nominal diameters from 10 mm to 50 mm. They are chemically resistant to various acids, alkalis, and numerous polar solvents.
Additional advantages:
- ozone resistance
- weather resistance
- aging resistance
- flexibility and robustness
The physiological safety of the inner surface is particularly noteworthy – it is FDA-compliant and thus suitable for contact with beverages, pharmaceuticals, and food. This makes the food hose also popular in the beverage industry, food production, and dairy processing, where it is often referred to as a “dairy hose.”
NBR hot-water hose
NBR versions are widely used in the beverage industry (soft drinks), food processing, dairy operations, and chemical processing. Their broad application range is explained by high temperature resistance from –30 °C to +100 °C (steam up to +164 °C) and pressure resistance up to 30 bar (+20 °C). The hose core is physiologically safe, manufactured in accordance with EU 1935/2004, BfR XXI:2002, and FDA CFR 21 §177.2600. Elasticity, weather resistance, and aging resistance are all excellent.
Double-jacket hot-media hoses are used for transporting particularly hot media such as hot water or hot chemicals. Despite good elastic properties, they feature outstanding abrasion resistance and mechanical stability. The permissible working temperature range is –20 °C to +180 °C (short-term +220 °C). In addition to numerous chemicals, the double-jacket hose is also resistant to mineral oils and fuels. The pressure resistance of 8 bar at +20 °C is ensured by an integrated fabric insert.
Silicone hot-water hose
Silicone products are well known for their high temperature resistance and rubber-elastic properties. High-temperature grades can withstand continuous use up to +250 °C, short-term up to +300 °C. Unsurprisingly, this elastomer is also used for hot-water hoses. These highly flexible silicone rubber versions combine excellent elasticity with high mechanical strength.
This group also includes silicone pressure tubes designed for pharmaceutical technology, medical technology, and process engineering. They are suitable for extreme temperatures and can be used as hot-water hoses up to +200 °C. As pressure carriers, PETP braids and glass fiber inserts are applied, enabling burst pressures up to 60 bar (+20 °C). These robust yet flexible hoses are physiologically safe and meet the requirements of:
- FDA (CFR 21 §177.2600)
- USP (Class VI)
- BfR (XV Silicone)
- European Pharmacopoeia
- NSF 51
They can therefore also be classified as food- and medical grade tubing.
Silicone pressure and high-temperature tubes are also available with steel wire braiding. This version can be used continuously between –50 °C and +190 °C (short-term up to +250 °C). The galvanized steel braid provides exceptional robustness, stability, and mechanical load capacity – while maintaining flexibility and relatively small bending radii. An additional glass fiber insert is integrated as pressure reinforcement.
SBR hot-water hose
Styrene-butadiene rubber is a soft and elastic polymer used in hot-water hoses across the following sectors:
- plant engineering
- process engineering
- power plant technology
- wastewater technology
- turbine engineering
- hot-water systems
These steam and water hoses are suitable for high temperatures (–20 °C to +100 °C, steam up to +164 °C) and can handle pressures up to 6 bar at +20 °C, ensured by the integrated synthetic fabric.
