Heat-resistant hoses; the best solution for the right application
09-10-2025
Heat resistance is quite a broad concept. A heat-resistant hose suitable for conveying hot liquids or gases is not necessarily suitable for use in a hot environment. And a hose that you want to protect against fire requires a different solution. Therefore, it's important to carefully consider the application and make the right choice. An overview of different applications of heat-resistant hoses.
Transporting hot gases or liquids with heat-resistant hoses
When you need to pump a medium such as steam, oil, or chemical liquids at high temperatures, you need hoses that can withstand heat and retain their mechanical properties (such as working pressure). Consider PTFE hoses or metal (stainless steel) hoses, both of which are suitable for withstanding high temperatures and pressure over the long term.
Using heat-resistant hoses in a hot environment
Sometimes it's not about the medium itself, but about the environment where the hose is applied. Think of production areas, installations near ovens, or engine compartments. In those circumstances, the hose must be protected against radiant heat or high ambient temperatures to remain safe and reliable in operation.
Protection against fire or external heat
In situations where the hose is exposed to open flames, sparks, or extreme external heat, extra protection is necessary. Some types of hoses have a heat-resistant outer wall. For hoses that do not have this, there are special fire sleeves: a flame-retardant protection that you slide over the hose. These fire sleeves form a barrier against heat and fire, enhancing the safety of both the installation and its users.

Frequently asked question
There are several types of heat-resistant hoses, such as: Stainless steel metal hoses: ideal for high pressure and temperature. Rubber hoses: with a heat-resistant outer layer for various applications. PTFE hoses: highly resistant to chemicals and high temperatures. Fire sleeves: protective covers that are slid over existing hoses to protect them from fire and sparks.
To give proper advice, we need the following information: the application and environment, the medium flowing through the hose, the minimum and maximum temperature of the medium, ambient temperature, maximum pressure or vacuum, hose length, inner diameter, type of connection on both ends, and, if applicable, the flow rate.
Yes, stainless steel metal hoses are highly resistant to very hot chemical substances. PTFE hoses are also resistant to hot and aggressive chemicals.
A fire sleeve is needed when the hose is exposed to open flames, sparks, or external heat. It protects the hose’s outer layer.
By applying a fire sleeve, a hose can be protected from fire and sparks. However, an existing hose cannot simply be made heat-resistant for pumping hot substances.
Yes, by using a double-walled hose or by electrically heating the hose to maintain the medium’s temperature.
