Product Description

Stainless Steel Wire Braided PTFE Brake Hose has become a mainstream fluid transfer solution for modern automobile brake systems, motorcycle brake upgrades and performance modification projects. This hose assembly adopts a three-layer composite structure: seamless extruded PTFE inner tube as the medium channel, 304 stainless steel wire braided layer as the pressure reinforcement, and polyurethane outer jacket as the protective shield. As a professional manufacturer of automotive fluid pipeline systems, HAOFA devotes to developing and producing reliable Stainless Steel Wire Braided PTFE Brake Hose. We implement full-process quality control from raw material screening to finished product inspection, providing stable brake hose products for global modification workshops, auto spare parts wholesalers and vehicle manufacturers.

The core inner tube of Stainless Steel Wire Braided PTFE Brake Hose is made of seamless virgin polytetrafluoroethylene (PTFE) material. PTFE features extreme chemical inertness, which hardly reacts with brake fluid (DOT 3/DOT 4), gasoline, engine oil and other automotive fluids. Conventional rubber and nylon brake hoses may absorb fluid over time, causing inner wall swelling, degraded braking performance and shortened service life. However, the smooth non-absorbent inner wall of the PTFE liner keeps the fluid channel dimensionally stable, reduces flow resistance and prevents impurity accumulation, delivering a firm, consistent brake feel throughout the whole service life of the hose.

Stainless Steel Wire Braided PTFE Brake Hose is manufactured with an inner diameter of 3.2 mm and an outer diameter of 7.5 mm, with a minimum bend radius of only 80 mm. The compact bend radius allows flexible routing along chassis frames, suspension arms and motorcycle handlebars without kinking, simplifying installation in space-limited brake systems. Custom sizes and cutting lengths are available on request to match different vehicle models and installation layouts. Every specification is produced with clear working pressure and burst pressure standards to guarantee braking safety under alternating temperature and pressure conditions.

All finished Stainless Steel Wire Braided PTFE Brake Hose will undergo strict factory tests, including hydraulic pressure resistance test, tightness leakage test and cyclic bending durability test. Defective products will be removed before shipment to ensure consistent quality for bulk orders. For packaging standards, finished cut hose assemblies are sealed into labeled transparent PE zipper bags. Large hose coils are wrapped by woven bags. Banjo fittings and accessories are packed with bubble film to avoid collision damage. All commodities will be loaded into reinforced export cartons.

HAOFA supports multiple international trade terms: FOB, CFR, CIF, and DAP. Accepted payment methods include T/T and sight Letter of Credit. Full prepayment is required for all orders. Stocked Stainless Steel Wire Braided PTFE Brake Hose can be dispatched within 7-10 working days. Customized orders will be arranged after payment confirmation, with a 7–15 working days production cycle. Our main loading ports include Qingdao Port and Tianjin Port.

Our stainless steel wire braided PTFE brake hoses are premium brake line solutions designed for vehicle manufacturers, motorcycle brake system assemblers, modification workshops and global auto parts distributors. Manufactured with a PTFE inner tube, 304 stainless steel wire braided reinforcement and polyurethane outer jacket, these hoses provide stable high-pressure performance and reliable fluid delivery. Available with chrome-plated banjo fittings in multiple color options, suitable for automobile and motorcycle hydraulic brake systems.

Technical Specifications

Materials & Finish

• Base liner: PTFE inner tube, chemically inert and non-absorbent for stable fluid delivery and firm brake feel
• Reinforcement: 304 stainless steel wire braided layer, delivers stable pressure resistance and burst protection
• Outer sheath: Polyurethane jacket, improves wear resistance and protects against oil, weather and road debris
• Optional: Custom length cutting, OEM marking, pre-assembled hose assemblies with banjo fittings available on request

Assembly & Installation

• Step 1: Measure and mark the target length. Cut the PTFE brake hose squarely with a dedicated hose cutter to prevent jagged edges.
• Step 2: Deburr the cut ends thoroughly and clean the inner bore to avoid seal failure and fluid contamination.
• Step 3: Slip the protective rubber boot and fitting components onto the hose end in the correct order before assembly.
• Step 4: Assemble the banjo fittings on both hose ends, then torque the banjo bolts to the manufacturer specification.
• Step 5: Perform a pressure leakage test before installation. Keep the circuit pressurized for several minutes and inspect all joints for seepage.
• Step 6: After installation, bleed the brake system completely to remove trapped air before road use.
