High Temperature Rubber Hose
Product Overview
Our high temperature rubber hose is engineered for demanding industrial applications where extreme heat and pressure are constant challenges. Constructed from premium synthetic rubber compounds reinforced with high-tensile braided textiles or steel wire spirals, this hose delivers exceptional thermal resistance up to 200°C continuous operation and intermittent peaks exceeding 250°C. Ideal for transferring hot fluids, gases, and steam in harsh environments, the high temperature rubber hose ensures reliable performance without degradation, cracking, or delamination.
Unlike standard rubber hoses, our high temperature rubber hose incorporates advanced EPDM or silicone inner linings that provide superior resistance to thermal aging, ozone, and chemical exposure. Available in a wide range of diameters from 1/4" to 4" and lengths up to 100 meters, it meets international standards such as SAE J30R9, DIN 2828, and ISO 7751. This makes it a go-to solution for industries requiring durability and safety in elevated temperature scenarios, from automotive manufacturing to petrochemical processing.
With a focus on seamless integration into existing systems, the high temperature rubber hose features smooth bore designs for optimal flow rates and minimal pressure drops. Its flexible construction maintains kink resistance even at high temperatures, ensuring uninterrupted operations and reduced downtime. Backed by rigorous testing in accredited labs, this hose guarantees longevity and compliance with global safety regulations.

Application Scenarios
The versatility of our high temperature rubber hose makes it indispensable across diverse industries. In automotive manufacturing, it excels in transferring hot coolant, hydraulic fluids, and exhaust gases during engine testing and assembly lines, where temperatures often exceed 150°C.
In the petrochemical sector, the high temperature rubber hose handles hot hydrocarbons, steam for cleaning, and chemical mixtures in refineries and distillation units, resisting degradation from aggressive media.
Food and beverage processing benefits from FDA-compliant variants for sanitary hot water and steam transfer in pasteurization and sterilization processes, ensuring hygiene and safety.
Within power generation, it supports boiler feed lines, turbine cooling, and geothermal applications, enduring cyclic heating and high pressures.
Additional scenarios include metal fabrication for hydraulic presses, aerospace for ground support equipment, and marine engineering for engine compartments. Its robust design minimizes leaks and failures, promoting operational efficiency in any high-heat environment.
Advantages
Choosing our high temperature rubber hose offers distinct advantages over conventional alternatives. Firstly, its advanced polymer formulation provides 50% longer service life in high-heat conditions, reducing replacement frequency and costs. Independent tests show zero elongation after 1,000 hours at 180°C, far surpassing industry averages.
Secondly, the hose's low thermal conductivity minimizes external heat transfer, enhancing worker safety and equipment protection. Its flexibility—retaining 90% at operating temperatures—facilitates easy routing in tight spaces without kinking.
Thirdly, superior adhesion between layers prevents blistering or separation, a common failure in lesser hoses. This ensures consistent performance under vacuum, surge pressures, or vibrations.
Environmentally, it's free of heavy metals and phthalates, aligning with sustainability goals. Cost-effectively, it delivers a ROI through reduced downtime and maintenance, with warranties up to 5 years.
Compared to PTFE or metal hoses, our high temperature rubber hose is lighter, more affordable, and easier to install, without compromising on pressure or temperature ratings.
