Choosing the right brake hose is a safety decision, not a marketing one. Too often it comes down to claims instead of evidence. This page gives you the evidence: three measured figures, all taken from Qingdao Jinyuan Automotive Tubing Co., Ltd.'s own test report (No. JY20260825-1) — tested to GB 16897-2022 and SAE J1401 — and every figure clearly exceeds the national-standard minimum while outperforming ordinary rubber hose. Match them to your duty cycle and vehicle type, and you will know exactly where this made of PTFE brake hose fits.

Q1. Where do these performance figures come from? Are they reliable?

A. All the data below comes from brake hose assembly performance testing carried out by Qingdao Jinyuan Automotive Tubing Co., Ltd. in accordance with national standard GB 16897-2022 and North American standard SAE J1401 (Test Report No. JY20260825-1; tested size: ID ≤3.2 mm). These are our own measured values, not marketing claims — and every one of them clearly exceeds the national-standard minimum and outperforms ordinary rubber hose.

Q2. Which customers should look at which figure?

A. Use the quick guide below to match each customer type to the data that matters most:

· Tuners / off-road riders (pedal feel) → Data ①: expansion only 45% of the national-standard limit

· Agricultural / construction (impact load) → Data ②: burst more than 40% above the national standard

· Coastal / cold-climate / water (corrosion) → Data ③: 480 h salt-spray, no base-metal corrosion

· North-America OEM export → Data ② + ③ + SAE J1401 test report

Q3. Does the hose feel soft under high pressure? How does the expansion compare?

A. Brake hose swells under pressure; the more it swells, the spongier the pedal and the slower the brake response — the most common weakness of ordinary rubber hose.

Best-fit duty: frequent heavy braking, need for a firm, responsive pedal feel.

Vehicle types: ATV, UTV, buggy, off-road motorcycles, modified sports cars, racing brake upgrades, light-truck and pickup brake lines, sport motorcycles.

Q4. Can it withstand pressure spikes without bursting?

A. A sudden pressure spike or over-pressure that exceeds the hose's burst limit causes burst and brake failure — the most dangerous risk, and where ordinary rubber hose often lacks safety margin.

Best-fit duty: heavy vibration, fluctuating operating pressure, environments with sudden pressure peaks.

Vehicle types: UTV/ATV rough-terrain operation; heavy-duty trucks and trailers; export OEM projects requiring strict burst-pressure review (e.g., SAE J1401, North America);tractors, harvesters and other agricultural machinery;excavators, wheel loaders and other construction equipment.

Q5. Will the fittings rust and leak in coastal, cold or wet conditions?

A. Rain, coastal salt fog, winter de-icing salt and mud corrode metal fittings starting from the crimp gap; the corrosion spreads and causes slow, hard-to-detect leakage.

Best-fit duty: coastal high-salt-fog areas, cold regions with road de-icing salt, long-term outdoor parking, frequent water or mud crossing.

Vehicle types: cars and commercials in coastal/sea-salt areas; brake lines of vehicles in cold winter de-icing-salt regions; agricultural and construction equipment parked outdoors or working in mud and water; ATV/UTV that regularly cross water or mud; export projects in coastal markets (SE Asia, Australia, etc.).

All performance figures above come from our own measured test report (No. JY20260825-1). A full report copy is available for customer verification, and sample testing and volume supply are supported. We let the data speak — every figure clearly exceeds the national-standard minimum and outperforms ordinary rubber hose.
