High-temperature · up to +400 °C
CP HiTex® 485
Mid-size variant of the CP HiTex family — galvanised steel clamp profile in 16 standard sizes from Ø 101.5 mm to Ø 350 mm. Specified for normal operation up to +400 °C with short-term peaks up to +500 °C. That places 485 between 480 (+280 °C) and 487 (+450 °C) as the practical choice when dimensions are focused on the mid-range and temperature sits in the +350–400 °C zone.

Why this hose?
Most of industrial high-temperature handling does not sit at +500 °C peak — it sits in a continuous working range between +300 and +400 °C. CP HiTex® 485 is built for exactly that zone. A galvanised steel spiral encased in a clamp profile provides shape stability and abrasion resistance without over-specifying on temperature.
The difference from sister products lies in the temperature zone and dimensional focus. 480 covers broader sizes but only to +280 °C; 487 goes higher in temperature (+450 °C) and is the typical mid-size workhorse; 486 has almost the same temperature as 485 but extends toward larger dimensions. 485 is the focused mid-segment: Ø 101.5–350 mm, +400 °C continuous.
The construction is vacuum- and low-pressure oriented like the entire clamp-profile family. The hose is not specified for positive working pressure. Thermal expansion when operating from room temperature to +400 °C is moderate but measurable — several centimetres per metre — and must be accounted for in installations where the hose is fixed at both ends.
High-temperature hoses are not pressure hoses. The CP HiTex series is designed for vacuum and low-pressure extraction of hot media — it is not specified for positive working pressure. Attempting to pressurise the hose above specified vacuum limits will deform the construction.
Thermal expansion must be considered in the installation — the hose changes length by several centimetres when operating from room temperature to +400 °C. Allow free length change or use expansion compensators.
Where it is used
The hose is used where temperature exceeds what polymer hoses can handle — typically in exhaust and extraction systems on industrial furnaces, boilers and engine test benches.
Typical installations are municipal sweeping vehicles with diesel engine exhaust, extraction from welding robots, and exhaust gas lines from furnaces in glass, ceramics and refractory industry.
In paper industry, glass industry, automotive industry the metallic construction is an advantage — it resists both thermal load and sparks from the process, where polymer materials would melt or ignite.
The formal name is CP HiTex® 485. In daily use, many call it "the mid-size CP HiTex", "the 400-degree hose" or "mid-range clamp profile". All three work.

485 = +400 °C continuous, dimensions Ø 101.5–350 mm, 16 sizes. 487 = +450 °C continuous, dimensions Ø 75–450 mm, 33 sizes. If temperature stays continuously below +400 °C and your size requirement is in the mid-segment, 485 is the focused solution. For higher temperatures or broader sizes, 487 is the right choice.

Note: Fields without a value (—) are not specified in the manufacturer's factsheet. Overpressure and underpressure are recommended operating limits; the product can be subjected to higher loads on request. Bend radius is measured along the inside of the hose. Contact us for full specifications or special variants.

Industries that use it
The hose is used across a wide range of industries — below is an overview of the most typical industries where CP HiTex® 485 is used:
In paper industry and glass industry the hose sits in drying installations and off-gas lines where temperature sits in the +350–400 °C zone. The moderate dimensional breadth (Ø 101.5–350 mm) fits the mid-segment of drying and extraction ducts — neither tight specialty extractions nor large main lines.
In automotive and test-bench systems it is connected to engine exhaust under controlled test conditions. In welding industries it is used for local welding fume extraction in processes where +500 °C peak is sufficient — typically MIG/MAG welding rather than the hottest TIG or plasma applications.
In glass, ceramics and refractory industries it handles hot gases at furnaces and firing processes. In HVAC and climate installations it sits in hot-air ducts. Across industries the common thread is that +400 °C is the upper continuous limit, and that the size requirement is focused around the mid-segment.
Custom lengths and assemblies
CP HiTex® 485 can be cut to length and assembled with couplings, cuffs and threads to fit your installation precisely. We produce complete hose assemblies with crimped ferrules, clamp collars or threaded connections, depending on what the process requires.
We advise on coupling types and assembly solutions suited to your specific application, so the installation is reliable and easy to maintain.
Frequently asked questions
How high a temperature can the hose handle?
The specific temperature range is shown in the factsheet for each variant — typically +400 to +500 °C in normal operation with short-term peaks higher. Exceeding the limit significantly reduces service life.
Can the hose be used at positive working pressure?
Not specified. The CP HiTex series is designed for vacuum and low-pressure extraction. Use at positive pressure requires specific approval from the manufacturer.
What makes the clamp profile construction special?
The clamp profile is the external steel band that is clamped between the spiral windings. It provides a smooth, mechanically robust outer wall that resists wear and thermal expansion better than unshielded spiral constructions.
Can the hose be used outdoors?
Yes, but UV and moisture will affect the galvanised steel spiral over time. For long-term outdoor installation it should be protected from direct weather — or a variant with stainless steel spiral can be selected.
Is the hose ATEX-approved?
No. The CP HiTex series is metallic construction without specific ATEX marking. For ATEX use at elevated temperatures, other variants are available — contact Particulair for guidance.
