About Qingdao Hainuo Machinery Production Co., Ltd. - Brake Hose Supplier in China

Qingdao, China hosts Qingdao Hainuo Machinery Production Co., Ltd., which currently lists five distinct products in its catalogue. The catalogue includes Ss braided brake hose, SAE J1401 rubber hydraulic brake hose, brake hose ends fitting, brake hose assembly, and low carbon steel tube. Each item falls under the broader automotive hydraulic and fluid‑conveyance categories that are typically classified under HS‑8 chapters for rubber and steel products. The supplier is identified as an imported tier with a harbor trust rating, indicating it operates through standard Chinese export channels.

The product list shows a focus on brake‑system components, ranging from raw tubing to complete assemblies. The Ss braided brake hose is a reinforced rubber hose with stainless‑steel braiding, while the SAE J1401 hose complies with the North American SAE J1401 standard for hydraulic brake lines. Brake hose ends fittings provide the mechanical interface to brake calipers or master cylinders, and the brake hose assembly combines hose and fittings into a ready‑to‑install unit. The low carbon steel tube is a separate steel‑based product that can serve as a structural or conduit element in various mechanical systems.

Product Range and Specialties of Qingdao Hainuo Machinery Production Co., Ltd.

The catalogue’s brake‑hose portfolio covers both reinforced braided constructions and standard rubber hoses built to the SAE J1401 specification. In the industry, braided hoses are commonly rated for pressures between 200 bar and 350 bar, with inner diameters from 6 mm to 20 mm and outer diameters up to 30 mm. SAE J1401 hoses typically use EPDM or nitrile rubber, meet a minimum tensile strength of 25 MPa, and must pass burst pressure tests at 2.5 times the working pressure. End fittings are usually made from forged steel or aluminum, featuring ISO 1102‑type connections, and assemblies are supplied pre‑fitted and crimped to reduce on‑site installation time. Low carbon steel tubes are generally produced to ASTM A53 or EN 10210 grades, with wall thicknesses ranging from 1 mm to 5 mm, and are used for fluid transport or structural reinforcement in machinery.

Trade and Export Information - Qingdao Hainuo Machinery Production Co., Ltd.

China is one of the world’s largest exporters of automotive hydraulic components, and Qingdao’s port provides direct access to Europe, North America, and Southeast Asia. Brake hoses and related fittings are normally classified under HS Chapter 87 (vehicles) or Chapter 73 (iron and steel products) depending on material, and shipments frequently use 20‑ft or 40‑ft containers with wooden pallets or bulk packaging. Buyers in the automotive OEM and aftermarket sectors typically request ISO 9001 quality‑management certification and compliance with SAE or ISO standards; however, such certifications are not listed in the supplier’s facts and should be verified. Common Incoterms for these goods are FOB Qingdao or CIF destination port, with standard freight forwarder handling for hazardous‑material labeling where required.

Sourcing from Qingdao Hainuo Machinery Production Co., Ltd. - Buyer Guidance

Importers should request product data sheets that detail hose construction, pressure rating, material composition (e.g., EPDM, nitrile, stainless‑steel braid), and conformity to SAE J1401 or equivalent standards. Test reports for burst pressure, tensile strength, and dimensional tolerances are standard verification documents for brake‑system hoses. For the low carbon steel tube, buyers normally ask for mill test certificates (MTC) showing chemical analysis, mechanical properties, and compliance with ASTM A53 or EN 10210. Because the supplier’s catalogue does not specify certifications, purchasers are advised to obtain copies of ISO 9001 or relevant automotive quality system certificates before confirming orders.

What types of brake hoses does Qingdao Hainuo manufacture?

The supplier lists Ss braided brake hose and SAE J1401 rubber hydraulic brake hose, covering reinforced stainless‑steel braid constructions and standard rubber hoses built to the SAE J1401 specification.

Are the brake hoses compatible with European vehicle standards?

The SAE J1401 hose meets North American standards; buyers targeting Europe should verify compliance with ISO 4422 or UNE‑EN standards, which can be confirmed through test reports or certificates.

What material is used for the brake hose ends fittings?

The catalogue mentions brake hose ends fitting without material detail; industry practice uses forged steel or aluminum, so buyers should request material specifications and mechanical test results.

Can I obtain a complete brake hose assembly from this supplier?

Yes, the supplier lists a brake hose assembly that combines hose and fittings into a ready‑to‑install unit, typically supplied pre‑crimped and ready for field installation.

What are the typical dimensions for the low carbon steel tube?

Low carbon steel tubes are commonly supplied in diameters from 10 mm to 100 mm with wall thicknesses between 1 mm and 5 mm, adhering to ASTM A53 or EN 10210 grades; buyers should request the exact size sheet.

Which certifications should I ask for before purchasing?

Buyers should request ISO 9001 quality‑management certification, any automotive‑specific certifications such as IATF 16949, and product‑specific test reports for pressure and tensile strength.

What packaging and shipping options are available?

Standard practice for brake hoses and steel tubes is bulk packing on wooden pallets inside 20‑ft or 40‑ft containers, with FOB Qingdao or CIF destination port terms commonly used.
