Shenzhen Autowellix Autoparts Co., Ltd. is a professional automotive parts manufacturer and exporter based in Shenzhen, China, specializing in high‑quality vehicle fluid lines and hose assemblies. With a strong focus on innovation, design, and precision manufacturing, Autowellix offers a wide range of products including coolant hoses, gearbox oil lines, steering fluid pipes, windshield spray hoses, and other critical automotive pipe solutions.
In the rapidly evolving landscape of automotive engineering, the SAE J20 standard serves as the bedrock for cooling system reliability. As a tier-1 and tier-2 supplier, Autowellix doesn't just meet these standards; we redefine them through "Information Gain" — providing our clients with deeper material insights, better thermal performance data, and superior longevity through "Experience, Expertise, Authoritativeness, and Trustworthiness (E-E-A-T)."
SAE J20 classifies hoses into several types (Class A to E). We specialize in Class A (High-Temperature Silicone) and Class D-1 (EPDM), ensuring resistance to electrochemical degradation (ECR) and extreme coolant temperatures ranging from -40°C to +175°C.
Utilizing high-tenacity Aramid (Kevlar) or Polyester fiber reinforcement, our hoses maintain structural integrity under high pressure and vacuum cycles, preventing wall collapse or bursting in heavy-duty applications.
Through 3D scanning and CAD modeling, Autowellix provides perfect-fit OEM/ODM replacements. This reduces installation stress and eliminates the risk of abrasion against adjacent engine components.
Autowellix is committed to providing durable, reliable, and high‑performance automotive piping systems that withstand extreme temperatures, high pressures, and rigorous driving conditions. Its products are widely used in passenger vehicles, commercial automobiles, and aftermarket applications worldwide. With strict quality control processes, from material selection to final inspection, Autowellix ensures every product delivers excellent service life and safety performance.
The transition toward New Energy Vehicles (NEVs) and Electric Vehicles (EVs) has fundamentally shifted the requirements for coolant hoses. While traditional ICE engines focus on high heat dissipation, EV thermal management systems require higher precision and lower permeability.
Development of ultra-low permeability hoses for battery cooling plates to maintain optimal operating temperatures for Li-ion cells.
Moving toward bio-based elastomers and 100% recyclable materials to align with the global automotive industry's Carbon Neutrality goals.
Integrating thin-film sensors within the hose walls to provide real-time data on pressure fluctuations and fluid health (Predictive Maintenance).
Operating out of the tech hub of Shenzhen, Autowellix leverages "Industry 4.0" principles to provide a competitive edge in global procurement. Our facility integrates automated extrusion lines and robotic assembly to minimize human error and maximize throughput.
AI-driven visual inspection for pinholes and surface defects.
Laser-etched batch coding for full lifecycle tracking of every hose.
Direct-from-factory pricing with optimized logistics via Shenzhen's port.
From CAD design to physical sample in under 10 business days.
Dedicated to customer satisfaction, Shenzhen Autowellix Autoparts Co., Ltd. supports OEM and customized solutions, providing tailored services to meet diverse market needs. The company’s global sales network and professional support teams enable efficient cooperation with partners across Europe, the Americas, Southeast Asia, and beyond.
Navigating the complex regulatory environment is a core competency of Autowellix. Our products are rigorously tested to meet:
EPDM is the industry standard for cost-effective, durable coolant hoses with excellent ozone and weather resistance. Silicone, under SAE J20 Class A, is preferred for extreme temperature environments (up to 200°C) and provides superior flexibility but at a higher price point.
We provide comprehensive technical data sheets (TDS), aging test reports, and finite element analysis (FEA) results. We don't just supply a part; we supply the engineering data that ensures system reliability.
Yes. Our in-house mold design and CNC tooling facility allows us to create complex multi-branch hoses and 3D formed pipes that match specific engine bay constraints perfectly.
Standard lead time for existing molds is 15-20 days. For new ODM projects, including mold development and initial samples, the typical timeline is 30-45 days.
