High-temperature · up to +400 °C
CP HiTex® 486
Large-bore variant of the CP HiTex family — galvanised steel clamp profile in 15 standard sizes from Ø 92 mm to Ø 400 mm. Like sister product 485, 486 is specified for normal operation up to +400 °C with peak up to +500 °C. The difference lies in dimensional focus: 486 extends toward larger sizes and is the choice when throughput is the dominant requirement.
- Up to +400 °C
- Galvanised steel
- Clamp profile construction
- Highly flexible
- Hot gases and vapours
- Cut to length
Why this hose?
When a high-temperature installation has to move large volumes of hot air or gas, dimension becomes the governing parameter. CP HiTex® 486 is the variant of the clamp-profile family focused on the 200–400 mm segment, where smaller sizes would give too high flow resistance. The construction is identical to 485 (galvanised steel, clamp profile) — it is the size choice that separates them.
Temperature-wise 486 sits in the same zone as 485: +400 °C continuous, peak +500 °C. That covers the practical mid-range where 480 is thermally under-specified and 487/483 are over-specified. The difference from 487 is primarily dimensional ranges: 487 has 33 sizes from Ø 75 to 450 mm; 486 has 15 sizes focused on the larger dimensions.
Like the rest of the clamp-profile family it is vacuum- and low-pressure oriented. The larger cross-sectional area combined with the highly flexible clamp-profile construction makes it particularly applicable where overall height and bend radius must be balanced against throughput. Thermal expansion is measurable when operating above +300 °C and must be accounted for.
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® 486. In daily use, many call it "the large CP HiTex", "the 486 hose" or "large-bore clamp profile". All three work.

The two hoses share temperature zone (+400 °C continuous, peak +500 °C) and construction. The difference is size: 485 focuses on Ø 101.5–350 mm across 16 sizes; 486 goes up to Ø 400 mm but starts at Ø 92 mm across 15 sizes. Choose based on the dimension you actually need.

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® 486 is used:
In paper industry and glass industry 486 typically sits in main lines on drying installations and off-gas systems where air volume is the governing parameter. The larger dimension from 200 mm upwards is necessary to keep flow velocity within design limits without the hose acting as a bottleneck.
In automotive and automotive test benches it is connected to large engine exhaust systems on test rigs where multiple cylinders feed the same extraction line. In glass, ceramics and refractory industries it sits in main lines at furnace off-gas where smaller dimensions would give too high flow resistance.
In HVAC and climate installations it is the choice for large hot-air systems in industrial spaces. In metalworking and forges it sits in central extraction systems. The common thread is that size is the governing parameter, not temperature — below +400 °C 486 would be over-specified if it were not specifically the size that dictated the choice.
Custom lengths and assemblies
CP HiTex® 486 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.
