Product Description

The Stainless Steel Braided Rubber Hose from Hengshui Speed Drive Technology Co., Ltd.-HaoFa Racing represents the ideal balance between rubber flexibility and stainless steel durability. At its core is a CPE (Chlorinated Polyethylene) rubber inner tube, selected for its superior resistance to heat, ozone, weathering, and a broad range of chemicals. Surrounding the CPE core is a tightly woven 304-grade stainless steel wire braid that dramatically increases burst pressure capability while providing outstanding abrasion, cut, and crush resistance. The 304SS braid also protects against rodent damage, weld spatter, and mechanical impacts in harsh industrial environments. Available in seven AN-standard sizes from AN-4 to AN-20, this hose is rated for significantly higher working pressures than un-braided alternatives and maintains flexibility for easy routing. It is the preferred choice for high-temperature oil lines, turbocharger coolant feeds, hydraulic system connections, and any application where rubber performance and steel durability must work together.

Key Features

• 304 stainless steel braided outer layer — provides exceptional burst strength, abrasion resistance, and protection against mechanical damage

• CPE (Chlorinated Polyethylene) rubber inner core — superior heat, ozone, and weather resistance compared to standard NBR, with broader chemical compatibility

• AN-standard sizing — available in AN-4 through AN-20, covering inside diameters from 5.56 mm to 28.5 mm for precise fitment in performance and industrial systems

• High pressure capability — working pressures significantly exceed un-braided rubber hose, suitable for demanding hydraulic and pressure-fed lubrication systems

• Corrosion-resistant construction — the 304SS braid resists rust, oxidation, and chemical attack in marine, outdoor, and industrial environments

• Temperature range — operates reliably from -40°C to +120°C (-40°F to +248°F) continuous service

Technical Specifications

Materials & Finish

The inner core is manufactured from CPE (Chlorinated Polyethylene), a synthetic rubber known for its excellent resistance to heat aging, ozone cracking, and weathering from -40°C to +120°C. A high-tensile synthetic fiber braid is embedded between the inner CPE tube and the outer 304SS braid, providing additional structural integrity and preventing the inner tube from extruding through the steel braid under pressure. The outer braid is woven from AISI 304 stainless steel wire (0.25–0.35 mm diameter), selected for its excellent corrosion resistance and formability. All raw materials are traceable to certified mills, and material certificates are available upon request.

Applications

• Turbocharger oil feed and coolant lines in high-performance engines

• Hydraulic return and suction lines in industrial machinery and mobile equipment

• Engine oil cooler connections subjected to high under-hood temperatures

• Fuel delivery lines where additional pressure rating and abrasion protection are required

• Chemical transfer lines in processing plants (compatibility-dependent on CPE rating)

• Marine engine compartments where corrosion resistance is critical

• Compressed air lines in workshop and manufacturing environments

Customization Options

Hengshui Speed Drive Technology Co., Ltd.-HaoFa Racing offers comprehensive customization for the Stainless Steel Braided Rubber Hose range. End fittings can be crimped in-house using AN, JIC, BSP, NPT, or metric thread standards. Straight, 45-degree, 90-degree, and custom-angle configurations are available. Hose length can be specified to the nearest centimeter. For OEM customers, custom branding via laser etching on fittings or inkjet printing on protective sleeves is supported. The in-house crimping and pressure testing equipment ensures that every assembly is leak-tested before shipment. MOQ for custom assemblies is 100 pieces per specification.

Packing & Logistics

Bulk hose without fittings: coiled and wrapped in PE film, packed in woven polypropylene bags. Assembled hoses with fittings: individually sealed in PE bags with protective caps on threads, packed in master cartons with foam dividers. Wooden crating available for heavy or high-value shipments. Port: Qingdao or Tianjin. Incoterms: FOB, CIF, CFR.

FAQ

Q: What is the advantage of CPE over standard NBR?

A: CPE offers superior resistance to heat aging, ozone cracking, and weathering compared to NBR. It also has better chemical compatibility with certain hydraulic fluids and hot oils. For applications exposed to outdoor conditions, engine bay heat, or aggressive chemicals, CPE provides longer service life.

Q: Is the 304SS braid truly rust-proof?

A: 304 stainless steel offers excellent corrosion resistance in most environments. It will not rust like carbon steel. For highly aggressive environments such as constant saltwater submersion or strong acid exposure, 316SS braid upgrades are available upon request.

Q: Can you supply complete assemblies with fittings installed?

A: Yes, we offer a full crimping service. Supply your fitting specifications and hose length requirements, and we will deliver pressure-tested, ready-to-install assemblies, saving you the time and equipment investment of in-house crimping.

Q: How do I choose the correct AN size?

A: AN sizes correspond to specific inside diameters. For example, AN-6 = 8.73 mm ID, AN-10 = 14.27 mm ID. Match the hose AN size to your system’s required flow rate. Our technical team can assist if you provide your flow requirements and fluid type.

Q: What pressure rating should I specify?

A: Working pressure varies by diameter. Select a hose with a working pressure at least 1.5–2x your system’s maximum operating pressure to account for pressure spikes. Our team can help confirm the pressure rating for your specific use case.
