THERMOID
Frequently asked questions
Common questions about THERMOID from 3G Electric.
What SAE standards do THERMOID fuel hoses meet?
THERMOID fuel hoses available through 3G Electric meet SAE J30R6 and SAE 30R7 standards. SAE J30R6 is a standard for low-pressure fuel hoses used in gasoline and diesel systems, while SAE 30R7 covers medium-pressure fuel hoses with a nitrile tube and cover. These standards define construction, burst pressure, and temperature resistance requirements. For example, the 5RMA1 hose (MPN 700025105) is rated to SAE J30R6, and the 5RLZ9 hose (MPN 667505225) meets SAE 30R7. Always verify the specific SAE designation for your application to ensure compatibility with fuel types and system pressures.
What is the temperature range for THERMOID air-brake hoses?
THERMOID air-brake hoses, such as the EPDM bulk hoses (SKUs 5RMA8, 5RMA2, 5RMA3), are rated for a temperature range of -40°F to 200°F. This range covers typical operating conditions for commercial vehicle air-brake systems, including cold-weather starts and engine-compartment heat. The EPDM material provides resistance to ozone, weathering, and heat aging. For applications outside this range, consult the manufacturer's specifications or consider alternative hose materials.
Are THERMOID gasoline hose assemblies available with pre-installed fittings?
Yes, 3G Electric supplies THERMOID gasoline hose assemblies with factory-installed fittings. Examples include the 44ZF93 assembly (3/4 in ID, 200 psi, 10 ft length) and the 44ZE95 assembly (1 in ID, 150 psi, 20 ft length). These assemblies come with nitrile/PVC or NBR/PVC tubes and Thermalon covers, and are designed for farm tank or transfer applications. The fittings are crimped to ensure leak-free connections. Specify the required end connections (e.g., NPT, barb) when ordering to match your system.
What is the working pressure of THERMOID farm tank gasoline hoses?
THERMOID farm tank gasoline hoses, such as the 44ZF47 assembly (3/4 in ID, 8 ft length), have a working pressure of 60 psi. This pressure rating is suitable for gravity-fed or low-pressure pump systems commonly used in agricultural refueling. Higher-pressure assemblies, like the 44ZF93 (200 psi) and 44ZE95 (150 psi), are available for applications requiring greater flow or longer hose runs. Always select a hose with a working pressure exceeding the maximum system pressure to ensure safety.
Can THERMOID fuel hoses be used with ethanol-blended fuels?
THERMOID fuel hoses with nitrile tubes, such as those meeting SAE J30R6 or SAE 30R7, are compatible with ethanol-blended fuels up to E10 (10% ethanol). For higher ethanol concentrations (e.g., E85), verify with the manufacturer or select a hose specifically rated for high-ethanol fuels. The nitrile material provides resistance to fuel permeation and swelling. For applications involving biodiesel or other alternative fuels, consult the hose's chemical compatibility data to avoid degradation.
