Import Auto Brake Part — Buy in Bulk from Supplier in China

Qingdao Hainuo Machinery Company supplies rubber brake hose sized at 3.2 mm x 10.5 mm (1/8f), a critical hydraulic component in automotive braking systems. The hose is constructed from industrial-grade rubber compound formulated to resist degradation from brake fluid exposure, heat cycling, and mechanical flexing. This specific dimension profile indicates a standard passenger-vehicle application, with the 3.2 mm inner diameter corresponding to common hydraulic brake line sizing and the 10.5 mm outer diameter providing adequate reinforcement wall thickness for system pressure containment.

The rubber compound is typically a blend of ethylene-propylene-diene monomer (EPDM) or similar elastomer, standard for brake hose construction due to its compatibility with glycol-based brake fluids and resistance to swelling. Reinforcement layers of braided textile or wire are standard in such hoses to prevent expansion under pressure, though the exact ply count and material should be confirmed with the supplier. The 1/8f thread designation suggests a fractional fitting size common in North American and some European vehicle specifications, requiring verification of thread pitch and sealing surface geometry for proper mating with caliper and master cylinder ports.

This brake hose serves original equipment manufacturers, aftermarket replacement distributors, and commercial vehicle repair facilities. Buyers should confirm the operating pressure rating, burst pressure, and compliance with applicable brake hose standards such as SAE J1401 or FMVSS 106. Temperature range, ozone resistance test results, and salt spray corrosion performance of the end fittings are additional specifications to request. Packaging, reel length options, and custom labeling capabilities should be discussed directly with Qingdao Hainuo Machinery Company, as these details are not specified in the listing.

Qingdao Hainuo Machinery Company is located at Room 605, No.17 Jiading Road, Qingdao 266031, Shandong Province, China. The supplier's profile indicates an imported tier classification with a harbor trust tier, which provides limited transactional history visibility. The response rate is recorded at 0.00% with an average response time of zero hours, suggesting either a newly registered account or inactive inquiry management on the platform. No verification documentation, factory audit results, or trade assurance coverage is indicated in the available profile data.

The company operates from Qingdao, a significant port city in northern China with established automotive component manufacturing clusters. The listing focuses specifically on rubber brake hose rather than a broad brake component portfolio. Buyers should conduct independent due diligence, including direct contact to assess technical capability, quality management system certification, and production capacity. The absence of response metrics necessitates proactive communication to establish supplier reliability before committing to trial orders.
