Ningbo Dafluid Machinery Industry & Trading Co., Ltd. is not just a supplier; we are your complete manufacturing partner. From hydraulic hose fittings and versatile fasteners to custom power steering assemblies, we bridge the gap between source factory capabilities and global supply chain needs.
Take a closer look at our manufacturing facility — from CNC machining centers to automated quality-control laboratories, ensure every hose fitting, bolt, and steering hose meets international standards.
Founded in Ningbo — China's premier manufacturing hub — Ningbo Dafluid Machinery Industry & Trading Co., Ltd. has evolved into a comprehensive source manufacturer and global solution provider. We specialize in three core divisions: high-pressure Hydraulic System Components (hose fittings, adapters, quick couplings, rubber hoses), industrial Fasteners (bolts, nuts, washers, threaded rods across all international standards), and precision Power Steering Hoses (engineered for Japanese, Korean, European, and American vehicle platforms).
Operating as an integrated industry and trade enterprise, our 15,000 m² production facility houses advanced CNC machining centers, precision cold heading machines for heavy-duty fasteners, automated hose assembly lines, and a fully equipped metallurgical laboratory. From raw material forging to final surface treatment, we maintain absolute control over the manufacturing process to support both scalable standard production and complex OEM/ODM customizations.
Manufacturing excellence requires rigid validation. Dafluid operates under strictly audited ISO 9001:2015 (Quality Management) and ISO 14001 (Environmental Management) systems. Every batch of hydraulic fittings, steering hoses, and structural fasteners undergoes rigorous pressure testing, dimensional inspection, and tensile strength analysis before shipment. Documentation packages — including material certificates, dimensional reports, and PPAP records — accompany our shipments to meet the exacting standards of global OEMs.
Our in-house engineering team specializes in fluid-system optimization, structural fastening solutions, and rapid-turn prototype development. Whether you need a standard DIN hydraulic adapter, a specialized high-tensile bolt, or a custom-routed power steering hose assembly, our engineers work directly with your procurement and design teams to deliver factory-direct solutions without the middleman markup.
Every Dafluid partnership begins with a direct technical consultation. We quote against your OE numbers, CAD drawings, or custom specification sheets. For custom components, our tooling lead time averages 15-30 days, with first-article samples shipped by air for your approval before mass production. For standard hydraulic fittings (JIC, ORFS, DIN, BSP) and universal fasteners, we maintain strategic inventory to ship within 7-15 business days of order confirmation.
We commit to three absolutes on every global shipment:
To provide reliable, precision-manufactured fluid and mechanical connections, offering complete solutions that drive our clients' success globally.
To be the globally preferred source factory for industrial fittings and fasteners, renowned for manufacturing excellence and seamless trade services.
