What Is a Carbon Free Hose?
A carbon free hose is a specialized rubber hose designed to be electrically non-conductive, making it ideal for applications where electrical insulation is critical. Unlike standard rubber hoses that may contain carbon black which conducts electricity, carbon free hoses are manufactured with special non-conductive compounds to prevent electrical current flow.
The construction features a highly electrically resistant EPDM inner tube that prevents electrical conductivity. This is reinforced with synthetic textile cord to ensure structural integrity while maintaining electrical insulation properties. The outer cover is made from an ozone and weather-resistant EPDM compound that provides excellent heat resistance. This makes our carbon free hose ideal for use in furnaces, electric furnaces, and other high-temperature applications where electrical safety is paramount.

Frequently Asked Questions — Carbon Free Hose
A carbon free hose is a specialized rubber hose designed to be electrically non-conductive, making it ideal for applications where electrical insulation is critical. Unlike standard rubber hoses that contain carbon black which conducts electricity, carbon free hoses are manufactured with special non-conductive EPDM compounds to prevent electrical current flow.
A quality carbon free hose is constructed with an electrically resistant EPDM inner tube formulated without carbon black. The reinforcement consists of synthetic textile cord, and the outer cover is made from heat and ozone-resistant EPDM compound. As a certified carbon free hose manufacturer in India, Flexihose uses only premium-grade compounds to ensure maximum electrical resistance.
The standard working pressure of a carbon free hose is up to 10 bar (145 PSI), with a minimum 4:1 safety factor between burst pressure and working pressure. This pressure rating is suitable for furnace cooling water and other industrial applications requiring electrical insulation.
Standard carbon free hose can withstand temperatures from -30°C to +120°C. This high temperature rating makes carbon free hose ideal for furnace cooling applications where hot water circulation is required while maintaining electrical insulation properties.

People Also Ask — Carbon Free Hose Troubleshooting & Safety
Why is electrical resistance important in carbon free hose?
Electrical resistance is critical because carbon free hose is used near electrical equipment and furnaces where conductivity could cause dangerous short circuits.
Can carbon free hose be used for steam?
No, standard carbon free hose is not designed for steam applications. It is specifically designed for water circulation in furnace cooling systems. For steam applications, use dedicated steam hoses rated for high temperatures and pressures.
How do I test the electrical resistance of carbon free hose?
Use a megohmmeter (insulation tester) to measure resistance between the hose inner surface and outer surface. Test should be performed before initial use and periodically during service. Flexihose carbon free hose is manufactured to a low leakage current of less than 20 microamp at 6000 volts DC.
What is the difference between carbon free and regular rubber hose?
Regular rubber hoses contain carbon black filler which conducts electricity.
How long does carbon free hose last?
The service life depends on operating temperature, pressure, and environmental conditions — Flexihose does not publish a fixed lifespan figure for furnace cooling applications. Regular electrical resistance testing is recommended.
What couplings are used with carbon free hose?
Carbon free hoses use standard water hose couplings such as camlock fittings, threaded connections, or flanges. Ensure couplings are also electrically insulated or use dielectric unions to maintain electrical isolation throughout the system.
