NUOENWEI Hightempflex – High Temperature Flexible Hose & Flexible Ducting for Extreme Thermal Applications
When your operation demands a high temperature flexible hose that withstands both scorching heat and freezing cold, choose NUOENWEI Hightempflex. This flexible ducting is designed for continuous use from -45°C to 300°C – and we offer heat-resistant upgrades to 400°C or even 1200°C for special orders.
The three-layer construction (outer abrasion protector, middle thermal insulation, inner smooth liner) guarantees efficient hot air delivery with minimal heat loss. The external galvanized or stainless steel spiral not only provides shape retention but also allows the duct to be dragged on the ground without wear – saving you time and replacement costs.
Whether you are venting exhaust from portable heaters, drying plastic granules, or extracting aggressive chemical fumes, NUOENWEI Hightempflex delivers flame resistance, chemical resistance (alkalis & acids), flexibility (bendable without kinking), and high tensile strength. Available in grey, yellow, black, blue, and custom colors for bulk orders.
NUOENWEI Hightempflex series
The NUOENWEI Hightempflex series is a premium high temperature flexible ducting engineered for extreme thermal environments. Made from multi-layered glass fiber with a thermally insulating middle layer, this hose maintains structural integrity and airflow efficiency from -45°C up to 300°C (with optional upgrades to 400°C or 1200°C). Available in inner diameters from 80mm to 1000mm and standard lengths of 3.6m or 7.6m, it combines outstanding flexibility with external abrasion protection from a rugged steel spiral. Whether you need to convey hot air, exhaust gases, or aggressive chemicals, NUOENWEI Hightempflex ensures safety, durability, and high thermal efficiency.

Product Advantages
Extreme Temperature Endurance
Operates reliably from -45°C to 300°C (or up to 1200°C with custom upgrade). Ideal for both cryogenic and high-heat environments.
Three-Layer Thermal Insulation
The middle insulation layer minimizes heat loss, making it highly efficient for hot air transfer and energy saving.
External Steel Spiral with Abrasion Protection
The rugged spiral wire allows the hose to be dragged on rough floors without damaging the fabric – perfect for construction sites and factories.
High Flexibility & Kink Resistance
Can be bent into tight spaces without collapsing, ensuring continuous airflow.
Flame Retardant & Chemical Resistant
Resists alkalis, metal acids, and many aggressive chemicals. Self-extinguishing properties meet safety standards.
Durable & Load-Bearing
The steel spiral provides structural strength, allowing the hose to bear limited external loads without deformation.
Waterproof & Fireproof
Suitable for outdoor and high-risk applications.
Cost-Effective
Excellent value – combines high temperature resistance, mechanical strength, and long service life.
Wide Diameter Range
From 80mm to 1000mm inner diameter, accommodating various airflow volumes.
Customizable
Length, color, insulation grade, and max temperature can be tailored for OEM orders.
Application Scenario
Temporary Heating & Ventilation
Connect to portable gas/oil indirect-fired air heaters for building construction, renovation, or repair sites. Also used for ground thawing and space heating.
Exhaust Gas Extraction
Ideal for engine manufacturing, motor testing, aircraft production, and military structures – removes hot exhaust fumes safely.
Plastic Industry
Works with pellet dryers, hopper loaders, and material conveying systems.
Printing & Compressor Systems
Used on printing presses, blowers, and compressors for hot air circulation or waste air removal.
Chemical & Fume Extraction
Resists aggressive media such as steam, smoke, and chemical vapors in chemical plants and industrial exhaust systems.
Abrasive Solid Transfer
Handles dust, fibers, and other abrasive particles without rapid wear – thanks to external steel spiral protection.
Portable & Indirect-Fired Heaters
Many heating units require ducting to distribute hot air to specific zones or to safely vent combustion byproducts outdoors. NUOENWEI Hightempflex is the perfect match.
Floor Drying & De-icing
Direct hot air precisely where needed for construction site ground preparation.
