THERMOID

About THERMOID

Thermoid is a manufacturer of industrial hose and fluid-transfer products with a history that traces back to the early 20th century. The brand is part of the HBD/Thermoid group, which operates manufacturing facilities in the United States and supplies hose, ducting, and accessories to industrial, transportation, and municipal markets. Thermoid's product range includes fuel hose, air-brake hose, EPDM hose, and other rubber and thermoplastic hose constructions. The company's products are used in applications such as fuel transfer, pneumatic systems, heavy-duty truck and trailer air-brake systems, and general industrial fluid handling. Thermoid hoses are often specified by SAE standards, such as SAE J30R6 and SAE J30R7 for fuel hose, which define performance requirements for low-pressure fuel lines. These standards cover burst pressure, tensile strength, and resistance to fuels including gasoline, diesel, and ethanol blends. Air-brake hose from Thermoid is constructed from EPDM (ethylene propylene diene monomer) rubber, which offers resistance to heat, ozone, and weathering. The air-brake hose is designed for compressed air systems in heavy-duty vehicles and industrial pneumatic applications, with temperature ratings from -40°F to 200°F. Thermoid fuel hose typically uses a nitrile tube for resistance to petroleum-based fuels and a temperature rating up to 257°F. The hose is available in various inside diameters, such as 3/16 inch, 1/4 inch, 5/16 inch, 3/8 inch, and 7/16 inch, and in bulk lengths of 25 feet or more. 3G Electric supplies Thermoid hose products to industrial buyers, including fuel hose and air-brake hose, with a focus on meeting specification requirements. The product line includes SKUs such as 5RLZ7, 5RLZ9, 5RMA1, 5RMA0, 5RLZ8, 5RMA8, 5RMA3, and 5RMC0, which cover common sizes and lengths. 3G Electric provides logistics support and can assist with identifying the correct hose for a given application based on inside diameter, length, temperature range, and SAE standard. The company serves plant engineers, maintenance managers, and procurement specialists who require documented compliance with industry standards. Thermoid hose products are used in fuel transfer, air-brake systems, and general pneumatic applications where flexible, durable hose is needed. The brand's focus on standard-compliant construction makes it suitable for maintenance, repair, and operations (MRO) inventories as well as original equipment applications. 3G Electric maintains inventory of Thermoid hose and can provide quotes for bulk orders or specific part numbers. The product data includes manufacturer part numbers, temperature ranges, and standards, allowing buyers to cross-reference against existing specifications. For fuel hose, the SAE J30R6 and SAE J30R7 standards indicate suitability for low-pressure fuel systems, while air-brake hose meets the demands of compressed air systems in mobile and stationary equipment. Thermoid's manufacturing background includes rubber compounding and hose extrusion, which supports consistent product performance. The brand's hose products are available in various constructions, including bulk lengths for cutting to size or assembly with fittings. 3G Electric does not manufacture Thermoid products but distributes them as part of its industrial equipment portfolio. The company can provide documentation such as certificates of conformance when required. Thermoid hose is typically used in applications where resistance to fuels, oils, and weather is important, and where flexibility and pressure ratings are specified. The air-brake hose is designed for heavy-duty truck and trailer systems, as well as industrial pneumatic lines that require a flexible connection. Fuel hose is used in fuel transfer, small engine fuel lines, and auxiliary equipment. 3G Electric's role is to supply these products with accurate specifications and logistics support, helping buyers match the right hose to their application. The product range includes both small-diameter fuel hose and larger air-brake hose, covering a variety of inside diameters and lengths. For procurement specialists, 3G Electric offers a single source for Thermoid hose and related industrial components, with the ability to quote based on part number or specification. The company's global shipping capabilities support customers in various regions, and its technical team can assist with product selection. Thermoid hose products are manufactured to meet SAE standards, which provides a baseline for performance and interchangeability. The brand's history in rubber manufacturing and its focus on industrial hose make it a recognizable name in fluid transfer and pneumatic systems. 3G Electric stocks Thermoid hose in common sizes and can source additional part numbers as needed. The product data provided includes SKU, manufacturer part number, inside diameter, length, temperature range, and standards, which allows buyers to verify compatibility. For fuel hose, the nitrile tube provides resistance to gasoline, diesel, and ethanol blends, while the cover protects against abrasion and environmental factors. Air-brake hose uses EPDM for resistance to heat and ozone, with a temperature range suitable for under-hood and exposed installations. 3G Electric supports the Thermoid line with inventory, logistics, and technical assistance, serving industrial customers who require standard-compliant hose for maintenance and production applications.
