Why EPDM Hose Is Ideal for Hot Water and Steam Applications
In industrial systems that continuously transport hot water and steam, selecting the right hose material is critical for safety, efficiency, and long-term performance. Among various hose materials, EPDM rubber hoses are widely recognized as the most commonly used choice for conveying hot water and steam.
As an experienced Chinese hose manufacturer, Utigoflex has supplied EPDM hoses for demanding applications worldwide. We will explain why EPDM hoses are suitable for hot water and steam transfer through the following points.
What is EPDM Hose?
EPDM hose (ethylene propylene diene monomer rubber hose) is a synthetic rubber hose made from a copolymer of ethylene, propylene, and non-conjugated diene. PVC hoses manufactured from this material offer weather resistance, high-temperature resistance, corrosion resistance, aging resistance, and excellent electrical insulation. Consequently, they are commonly used in automotive, construction, chemical, food, and pharmaceutical industries. They are also suitable for conveying water, steam, weak acids/alkalis, refrigerants, and other media.
Why Choose EPDM Hose?
-
Exceptional High-Temperature Tolerance
EPDM hoses are frequently used in hot water and steam applications due to their outstanding heat resistance. EPDM rubber typically withstands temperatures ranging from -40°C to +150°C, with some grades capable of handling up to 210°C.
-
Superior Aging Resistance and Weatherability
Compared to other rubber materials, EPDM’s greatest advantage lies in its outstanding resistance to ozone, UV radiation, and aging. For long-term use in hot water circulation systems or steam environments, hoses must withstand prolonged exposure to high-temperature moisture. EPDM rubber excels in such conditions, significantly extending service life and reducing replacement frequency.
-
Strong Chemical and Water Resistance
EPDM hoses exhibit exceptional tolerance to water, steam, and various mildly corrosive chemicals, making them ideal for hot water conveyance, cooling systems, and food-grade hot water applications. Utigoflex’s EPDM industrial hoses are specially engineered to maintain stable performance in persistently humid conditions without swelling, cracking, or degradation.

Core Difference Point Analysis
- Temperature Limit:
Steam hoses offer the highest heat resistance, withstanding temperatures up to 210°C. In contrast, standard air and water EPDM hoses reach their limit near 100°C. - Working Pressure Limit:
Steam hoses and hot water hoses typically feature reinforced construction, providing significantly higher pressure resistance than standard air and water hoses.
FAQs
Q1: Can EPDM hose be used for continuous steam applications?
Yes. EPDM steam hose is suitable for low- to medium-pressure steam and hot water systems when properly reinforced.
Q2: Is EPDM hose safe for potable hot water?
Certain EPDM hoses are suitable for potable hot water, depending on formulation and certifications.
Q3: How long does an EPDM hose last in hot water systems?
With proper use, EPDM hose can last several years due to its excellent aging resistance.
