Product Description

PTFE Nylon Braided Hose has become a mainstream fluid transfer solution for modern automotive performance refitting, motorcycle upgrading and amateur racing projects. This hose assembly adopts a double-layer composite structure: seamless extruded PTFE inner tube as the medium channel and high-strength nylon fiber braided layer as external reinforcement. As a professional manufacturer of automotive fluid pipeline systems, HAOFA devotes to developing and producing reliable PTFE Nylon Braided Hose. We implement full-process quality control from raw material screening to finished product inspection, providing stable tubing products for global modification workshops, auto spare parts wholesalers and racing engineering teams.

The core inner tube of PTFE Nylon Braided Hose is made of seamless virgin polytetrafluoroethylene material. PTFE features extreme chemical inertness, which hardly reacts with gasoline, diesel, ethanol-mixed fuel, hydraulic brake fluid, transmission fluid, engine lubricating oil and cooling liquid. Conventional rubber hoses will gradually expand, soften or crack after long-time contact with oil and fuel, leading to leakage risks. However, the smooth inner wall of the PTFE liner will not absorb liquid medium. It reduces fluid flow resistance and prevents impurity accumulation inside pipelines, extending the service cycle of the whole pipeline system greatly.

We provide full-size selection for PTFE Nylon Braided Hose covering AN3, AN4, AN6, AN8, AN10， AN12，AN16，AN20 to satisfy diverse flow requirements. AN3 and AN4 specifications are mainly used for motorcycle brake pipelines and small vacuum circuits of turbochargers. AN6 and AN8 are the most widely used specifications for fuel supply pipelines, transmission oil cooler lines and turbo oil feed lines on modified passenger vehicles including BMW, Audi and Volkswagen. Larger AN10 and AN12 sizes are suitable for high-flow fuel delivery systems and oil circulation pipelines of high-displacement racing engines. Every specification of PTFE Nylon Braided Hose is designed with clear rated working pressure and minimum burst pressure standards to guarantee driving safety under alternating temperature and pressure conditions.

All finished PTFE Nylon Braided 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. Supporting AN adapters and hose ends 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 PTFE Nylon Braided 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 PTFE nylon braided hoses are premium fluid transfer solutions designed for motorsport enthusiasts, auto modification workshops and global automotive parts distributors. Manufactured with PTFE inner liner, internal stainless steel braided reinforcement and outer nylon braided shield, these hoses provide reliable chemical resistance. Available in AN4, AN6, AN8, AN10, AN12 sizes. Easier to assemble than traditional stainless steel braided hose, suitable for fuel systems, methanol, engine oil, E85, coolant and vacuum applications.

Technical Specifications

Materials & Finish

Base liner: PTFE inner, chemically inert to fuels, alcohols and coolants

Reinforcement: 304 stainless steel braided wire, delivers stable pressure resistance

Outer sheath: Braided nylon shield, improves wear resistance and simplifies assembly

Optional: Custom length cutting, OEM marking and pre-assembled hose assemblies available on request

Assembly & Installation

Step 1: Measure and mark the target length. Cut the PTFE braided hose squarely with a dedicated cutter to prevent jagged edges.	Step 2: Neaten loose outer braided fibers at the cut end and fully deburr the inner PTFE tube to avoid seal failure.	Step 3: Slip the ferrule and outer nut onto the hose beforehand.
Step 4: Repeat the procedures above to assemble fittings on both hose ends. Step 5: Perform a pressure leakage test before use. Keep the pipeline pressurized for several minutes and inspect all joints for seepage.	Step 5: Perform a pressure leakage test before use. Keep the pipeline pressurized for several minutes and inspect all joints for seepage.	Step 6: Application
