Import Air Hose Black Textile Reinforced Rubber Hose — Buy in wholesale FOB from Supplier in China

This black textile reinforced rubber hose is manufactured by Hebei Tonex Rubber And Plastic Products Co., Ltd. in Cangzhou, Hebei Province, China, designed specifically for industrial transmission of oxygen and acetylene (ethyne) gases. The construction features a black NR and SBR synthetic rubber inner tube, reinforced with high tenacity textile fibre for pressure containment, and finished with a synthetic rubber cover in red, blue, or green colour options. The standard temperature range spans from minus 20 degrees C to plus 45 degrees C, with an EPDM variant extending operational capability from minus 20 degrees C to plus 120 degrees C for elevated temperature environments. This hose targets welding and fabrication operations where reliable gas distribution under pressure is critical to operational safety and efficiency.

The NR and SBR synthetic rubber inner tube provides elasticity and resistance to gas permeation, with SBR contributing abrasion resistance and NR delivering flexibility at low temperatures. High tenacity textile fibre reinforcement, typically polyester or nylon yarn braided or spirally wound, prevents longitudinal expansion and burst under working pressure. The synthetic rubber cover protects against mechanical abrasion, UV degradation, and contact with workshop chemicals. For the EPDM variant, the inner layer or outer cover substitution offers superior ozone resistance and thermal stability, making it suitable for outdoor installations or applications near heat sources where standard NR/SBR compounds would harden and crack. Typical working pressures for industrial gas welding hoses range from 10 to 20 bar, with burst pressures minimum 3 times working pressure, though exact ratings must be confirmed with the supplier.

Primary applications include oxy-acetylene welding and cutting equipment, gas distribution systems in metal fabrication shops, and industrial maintenance operations requiring flexible gas transfer lines. The colour-coded cover options (red for acetylene, blue for oxygen per standard practice) assist in gas line identification and safety compliance. Buyers include welding equipment distributors, industrial gas suppliers, and procurement departments for shipyards, construction, and automotive manufacturing facilities. B2B buyers should confirm working pressure ratings, connection thread specifications (typically BSP or NPT), and compliance with national gas hose standards such as EN 559, ISO 3821, or BS 3212. Trade terms, volume pricing, and lead times are not disclosed and require direct negotiation with Hebei Tonex.

Hebei Tonex Rubber And Plastic Products Co., Ltd. is located at No.806 Jichun Building, Huanghe West Road, Yunhe District, Cangzhou City, Hebei Province, China, postal code 061000. The supplier holds a harbor trust tier with a response rate of 0.00 percent and no recorded average response hours, indicating limited platform engagement. Cangzhou's location within Hebei Province positions the company near China's rubber products manufacturing belt, with historical specialisation in industrial hose and sealing products for domestic and export markets. The company's product focus encompasses rubber and plastic products with specific emphasis on industrial gas transmission hoses.

The available profile does not disclose factory size, production capacity, year of establishment, revenue figures, employee count, or third-party quality certifications such as ISO 9001. Buyers should independently verify manufacturing capabilities, including whether the supplier operates their own extrusion and vulcanisation facilities or sources components from subcontractors. No client references, export destinations, or case studies are present in the source data. Prospective buyers are advised to request a factory audit, evaluate sample hoses for pressure testing and dimensional accuracy, and establish direct communication channels outside platform messaging to ensure responsive account management during production and shipment phases.
