Product Description

Hengshui Speed Drive Technology Co., Ltd.—HaoFa Racing Braided Rubber Hose Assemblies are factory-crimped, pressure-tested fluid transfer lines that eliminate the complexity, waste, and leak risk of field assembly. Each assembly pairs a high-performance braided rubber hose with precision AN flare fittings, providing a clean, professional connection that maximizes flow and simplifies installation. The hose body features a multi-layer construction: an oil-resistant NBR inner tube, a high-tenacity synthetic textile reinforcement layer, and a tightly braided outer cover available in stainless steel wire or nylon fiber. Stainless steel braided assemblies offer superior burst pressure and cut resistance for extreme motorsport and industrial environments. Nylon braided assemblies deliver comparable pressure performance with significantly improved abrasion resistance, UV durability, and lighter weight for outdoor, agricultural, and construction applications. Full flow 90° elbow fittings are standard on both ends, with straight, 45°, and custom configurations available. Gold anodized AN swivel nuts provide tool-free, leak-free connections compatible with all AN-standard male flare adapters. Available in AN-4 through AN-12 sizes in standard and custom lengths from 30 cm to 6 meters.

Key Features

• Factory-crimped and pressure-tested — each assembly is verified at 1.5× working pressure before shipment, eliminating field assembly risk
• Multi-layer hose construction — NBR inner tube + synthetic textile reinforcement + braided outer cover (stainless steel or nylon) for maximum durability
• Full flow AN fittings — precision-machined 90° elbow or straight connectors with gold anodized swivel nuts for unrestricted fluid flow
• Two outer braid options — 304 stainless steel braid for maximum burst pressure and cut resistance; nylon braid for abrasion resistance, UV durability, and lighter weight
• AN-standard sizing — available in AN-4 through AN-12 with inside diameters from 5.56 mm to 17.47 mm
• Wide temperature range — operates reliably from -40°C to +150°C (-40°F to +302°F) for stainless steel, -40°C to +120°C for nylon
• Leak-free design — 37° flare seat interface ensures positive seal without thread sealant or O-rings

Technical Specifications

Materials & Finish

The hose body is manufactured with an NBR (Nitrile Butadiene Rubber) inner tube and synthetic textile reinforcement, engineered for consistent pressure containment across the full operating temperature range. The outer braid is available in two materials: 304 stainless steel wire (silver finish) for maximum burst strength and cut protection in motorsport and industrial environments, and high-tenacity nylon fiber (black, matte texture) for superior abrasion resistance, UV stability, and lighter weight. Both braid types are tightly woven to eliminate hose expansion under pressure and protect the structural layers beneath. All fittings are CNC-machined from 6061-T6 aluminum billet with black anodized bodies and gold anodized swivel nuts for corrosion resistance and visual identification. The 37° flare seat is precision-ground to ensure a metal-to-metal seal with standard AN male adapters.

Applications

• Automotive fuel injection and carbureted fuel delivery systems

Customization Options

Hengshui Speed Drive Technology Co., Ltd.—HaoFa Racing supports full customization. Custom AN sizes outside the standard -4 through -12 range can be produced with a one-time tooling investment. Straight, 45°, 120°, and custom-angle fittings are available. Nylon braid colors (red, blue, yellow, green) are available for volume orders exceeding 500 assemblies. Private labeling with laser-engraved fitting markings and printed hose identification is supported. Custom assembly lengths from 20 cm to 12 meters can be specified. MOQ for fully custom configurations is 200 assemblies.

Packing & Logistics

Each assembly is individually sealed in a PE protective sleeve with end caps, labeled with part number, AN size, length, and pressure rating, and packed in export-grade corrugated master cartons. Bulk orders shipped on pallets with protective corner boards and stretch wrap. Port: Qingdao or Tianjin. Incoterms: FOB, CIF, CFR.

FAQ

Q: What’s the difference between stainless steel braid and nylon braid?

A: Stainless steel braid offers 20–30% higher burst pressure and excellent cut/impact resistance, ideal for exposed motorsport installations. Nylon braid delivers superior abrasion resistance, UV stability, and is approximately 30% lighter, making it the better choice for outdoor, agricultural, and weight-sensitive applications where hoses are dragged across surfaces.

Q: Are these assemblies tested?

A: Yes. Every assembly undergoes a 1.5× working pressure hydrostatic test before shipment. Individual test records are available upon request with batch traceability to raw material lots.

Q: Can you match custom lengths and fitting angles?

A: Yes. Custom lengths from 20 cm to 12 meters, and fitting angles including 0°, 45°, 90°, 120°, and 180° are available. Provide a dimensional drawing or sample for exact replication.

Q: What’s included with each assembly?

A: Each assembly includes the crimped hose with pre-installed AN swivel fittings on both ends. Protective dust caps are fitted for shipping. No additional hardware or adapters are included unless specified.

Q: What information do you need for a quotation?

A: Please provide: AN size or inside diameter, outer braid preference (stainless steel or nylon), assembly length end-to-end, fitting angle on each end, total quantity, and shipping terms (FOB/CIF). Response within 24 hours.
