When a turbocharged engine generates over 500 horsepower on the dyno, every component in the oil delivery system is pushed to its absolute limit. Recognizing the critical demands of high-performance lubrication circuits, Hengshui Speed Drive Technology Co., Ltd.-HaoFa Racing today announced the release of its new braided oil hose assembly series, featuring advanced 304SS plus PTFE/CPE construction and innovative aluminum quick-release connectors that combine racing-grade durability with rapid tool-free servicing.
A standout feature of the new assembly is the integrated aluminum quick-release connector system. Machined from high-grade 6061-T6 aluminum with a black anodized finish, these connectors enable tool-free connection and disconnection in seconds—a critical advantage during race pit stops, field maintenance operations, and rapid prototyping scenarios. The quick-release mechanism incorporates a positive-locking design that audibly clicks into place, providing tactile confirmation of a secure connection. Each connector is rated for the full working pressure of the hose assembly and has been tested through more than 10,000 connect-disconnect cycles without degradation. The lightweight aluminum construction reduces overall system weight by approximately 40 percent compared to equivalent steel connectors.
The oil hose assembly has been extensively tested in real-world engine bay environments, where tight clearances, radiant heat from exhaust manifolds, and constant vibration present challenging operating conditions. The 90-degree elbow fittings are specifically designed to facilitate clean routing in confined spaces, reducing the need for additional adapters and minimizing potential leak points. In dyno testing with turbocharged engine configurations producing over 500 horsepower, the hose assemblies maintained consistent oil pressure with zero measurable flow restriction across a temperature range of -40°C to +200°C. Independent laboratory testing confirmed that the PTFE inner core exhibits less than 0.1 percent swelling after 1,000 hours of continuous exposure to synthetic engine oil at 150°C.
To simplify ordering and installation for distributors and performance shops, the company offers the oil hose assemblies in complete kit configurations. Each kit includes a pre-assembled hose with connectors installed at both ends, additional spare fittings for custom routing modifications, and detailed installation instructions. The nylon braided outer layer featured on select models provides enhanced abrasion resistance and a clean, professional appearance that complements high-end engine bay aesthetics. For volume buyers, mixed pallet shipping with flexible SKU combinations is available, enabling distributors to stock a comprehensive range of configurations while optimizing shipping costs and minimizing inventory complexity.
The launch of the braided oil hose assembly series reflects the company’s ongoing investment in research and development. Its dedicated R&D facility houses advanced testing equipment including dynamic pressure cycling rigs, thermal shock chambers, and salt spray corrosion testers. This infrastructure enables rapid prototyping and validation of new designs, with typical turnaround from concept to production-ready samples achieved in under 30 days. The company actively solicits feedback from distribution partners and end users to identify emerging needs and drive continuous improvement in product design and manufacturing processes.
