Import Brake Hose Assembly — Buy in Bulk from Supplier in China

This brake hose assembly is a flexible hydraulic conduit designed to transfer brake fluid from the master cylinder to the wheel brake units under sustained high pressure. The assembly comprises a reinforced rubber or thermoplastic inner tube, braided textile or stainless-steel reinforcement layers, and a weather-resistant outer cover, terminated with crimped metal fittings. Qingdao Sunsong Co., Ltd manufactures this component at its facility in Wangtai Lingang Industrial Park, Jiaonan, Qingdao, Shandong Province. The source description indicates construction with industrial-grade materials and testing for reliability, though no specific SAE J1401 or FMVSS 106 compliance figures are stated.

Standard brake hose assemblies for passenger and commercial vehicles typically withstand operating pressures of 2,000 to 3,500 psi (13.8 to 24.1 MPa) with burst pressures exceeding 8,000 psi, though buyers should confirm the exact pressure ratings with the supplier. The reinforcement usually consists of one to three braids of polyester, rayon, or stainless steel, depending on the application class: single-braid for light vehicles, double or triple for heavy-duty trucks. The inner liner must resist degradation from glycol-based brake fluids (DOT 3, DOT 4, or DOT 5.1) and maintain volumetric expansion within SAE-specified limits to prevent spongy pedal feel. Typical outer covers employ chloroprene (CR), ethylene-propylene-diene (EPDM), or polyvinyl chloride (PVC) compounds rated for temperatures from -40°C to +120°C.

Primary buyers include original equipment manufacturers (OEMs) of passenger cars, light commercial vehicles, and heavy trucks, plus aftermarket distributors and large independent repair chains. The assembly is critical in brake systems where rigid tubing cannot accommodate suspension travel or steering articulation. Sourcing from Qingdao Sunsong requires verification of their exact product certifications, response rate statiistics show 0.00% response rate with zero average response hours, so direct contact reliability needs assessment. Trade terms mentioned in source materials include FOB and CIF options, though precise Incoterms, MOQ, and lead times must be confirmed directly with the supplier.

Qingdao Sunsong Co., Ltd operates from Wangtai Lingang Industrial Park in Jiaonan, Qingdao, within Shandong Province, a major automotive component manufacturing cluster in northern China. The supplier is classified under an imported tier with a harbor trust designation. Response signals are notably weak: the response rate is recorded at 0.00% with an average response time of zero hours, indicating either a new listing, dormant account, or data collection gap rather than active engagement. The company profile as presented does not state years in operation, factory floor area, employee count, revenue figures, or named OEM clients.

The listing positions Qingdao Sunsong as a manufacturer of brake hose assemblies for automotive applications, with claimed certifications including ISO and CE marks, though specific certificate numbers, scopes, and issuing bodies are not provided. No information is given about in-house testing capabilities, production capacity, or export experience to specific markets. Buyers should independently verify factory existence, quality management system certification status, and product-specific test reports before committing to orders. The absence of response history suggests due diligence should include direct factory audit or third-party verification rather than reliance on platform-assigned trust indicators alone.
