Water and light fluids

Liquid hoses

Hoses for water, antifreeze and low-pressure liquids in industry, agriculture and municipal installations. Suitable for irrigation systems, cooling circuits, drainage and pump applications where temperature, ATEX and food approval are not the primary requirements.

Temperature is the single parameter most often under-specified on a factsheet. The manufacturer lists two numbers: a continuous service temperature and a peak temperature. The difference is round-the-clock versus minutes, and running close to peak for hours degrades the material faster than anyone expects.

On high-temperature installations, material choice must reflect the actual thermal profile across the entire duty cycle, not just the peak number. We distribute hoses in silicone, glass-fibre-reinforced silicone, and stainless steel, where the manufacturer's factsheet specifies both continuous and peak verbatim.

On this page you will find the hoses we recommend for hot media — from hot air in ovens through steam treatment to engine exhaust. Filter on max temperature and material in the left column to narrow the list to those hoses that match your temperature requirement.

Material choice is driven by the thermal profile, not by the peak number

Most failures we see on high-temperature installations are not about the hose being unable to handle the temperature. They are about the hose being able to handle it sometimes, but not 24/7. The material grows tired from repeated thermal cycling and from sustained exposure close to the peak limit.

Silicone

Standard silicone typically handles -60 °C to +200 °C continuously and short-term peaks up to 250 °C. It is flexible, has good chemical resistance and is cost-effective. The limit is exhaust temperatures or direct flame exposure, where the material degrades quickly.

Glass-fibre-reinforced silicone and glass-fibre-insulated hose

For temperatures from 250 °C up to around 600 °C, glass fibre serves as the thermal barrier. The hose may be glass-fibre-reinforced internally or wrapped in a glass-fibre cover externally. The internal medium temperature and the external surface temperature can differ markedly — that is what the insulation is for.

Metal hose

Corrugated stainless steel (typically AISI 316) handles continuous service up to 700-1000 °C, depending on alloy. It is stiffer than silicone, conducts vibrations and requires mechanical decoupling where that matters. In return, it is unavoidable where temperature exceeds silicone's peak, or where the hose is exposed to sparks.

Fire ratings: what B1 and V2 mean

DIN 4102-B1 and UL94-V2 are both fire classifications for flame-retardant materials. They state that the material does not support sustained flame after the ignition source is removed. They are NOT the same as "fire-stopping" or "non-combustible". Areas with direct flame exposure typically require metal hose or specialist products beyond these ratings.

Questions we are asked often

What is the difference between continuous and peak temperature?

Continuous service temperature is the maximum the hose can handle 24/7 throughout its lifetime. Peak (or short-term) temperature is the higher limit it can handle for a limited time — typically minutes to a few hours. Running close to peak for hours degrades the material faster than expected, even though the peak number is higher than the actual temperature.

Can silicone hoses be used for exhaust?

Standard silicone typically handles up to 250 °C continuously. Vehicle exhaust gas is often 400-700 °C at the manifold, which is too hot for plain silicone. For exhaust, use glass-fibre-reinforced silicone, glass-fibre-insulated hose, or metal hose. Check the manifold temperature before choosing material.

How do I prevent kinking at high temperature?

Materials soften at high temperature, and bend radius worsens. Use embedded helix (steel or glass fibre) to keep the hose open, or pick a construction with extra wall thickness. The factsheet specifies minimum bend radius — that figure applies at nominal temperature, not at peak.

What does DIN 4102-B1 mean?

DIN 4102-B1 is the German fire classification for building materials that are flame-retardant (schwer entflammbar). A class B1 material must not support sustained flame after the ignition source is removed. UL94-V2 is the US equivalent. Both ratings matter where a hose must be fire-resistant, though not necessarily fire-stopping.

Should I choose silicone or metal?

Silicone is flexible, lighter and easier to install — good for vibrations and lower temperatures. Metal hose (typically corrugated stainless steel) handles higher temperatures (700-1000 °C) but is stiffer and conducts vibrations. Pick metal when temperature exceeds silicone's peak, or where the hose is exposed to direct flame.
