Import Big Diameter Hydraulic Rubber Hose — Buy in Bulk from Supplier in China

This big diameter hydraulic rubber hose from Happy Technology & Development Co., Ltd. in Tianjin, China, is built around an NBR inner tube with a smooth black finish, fine wire reinforcement with electrical conductivity, and a synthetic rubber cover. The hose operates across a temperature range of -20°C to +45°C and is rated for conveying industrial water, waste water, seawater and agricultural irrigation fluids. A defining characteristic is its dual pressure performance, capable of withstanding both positive pressure and vacuum conditions down to -80 kPa (600 mm mercury column) without flattening or delamination.

The NBR (nitrile butadiene rubber) inner tube provides standard oil and water resistance for fluid transfer applications, while the fine wire reinforcement delivers structural integrity and electrical conductivity for safety in environments where static discharge may be a concern. The synthetic rubber outer cover offers abrasion and weathering protection typical of industrial suction and discharge hoses. The burst pressure is stated to be at least three times the working pressure, which is standard engineering practice for rubber hose safety margins but buyers should request the specific working pressure rating in bar or MPa for their application.

This hose suits municipal water management, marine operations, agricultural irrigation systems and industrial wastewater handling. Importers targeting construction dewatering, port services or large-scale farming operations will find the vacuum capability particularly relevant for suction duties. Given the supplier's harbor trust tier and 0.00% response rate with zero recorded average response hours, buyers should expect to initiate contact through multiple channels and allow extended time for quotation and sample requests. All pressure ratings, vacuum limits and dimensional specifications require written confirmation before order placement.

Happy Technology & Development Co., Ltd. is located on Zhujiang Road in Hexi District, Tianjin, China. The company holds a harbor trust tier, which represents a baseline verification status on the platform. The response rate is recorded at 0.00% with an average response time of zero hours, indicating no response history is available through the platform interface. The listing presents a single product focused on large-diameter hydraulic rubber hose for fluid transfer with vacuum capability.

The supplier profile does not disclose establishment year, staff count, factory size, annual revenue, clientele or certification holdings. No ISO, API or product-specific certifications are mentioned in the available data. Buyers should conduct independent due diligence, request business registration documents and verify production capabilities directly. The Tianjin location offers proximity to the port of Tianjin, a major northern Chinese maritime hub, which may offer logistics advantages for export shipments depending on the supplier's actual export experience.
