Product Overview
PTFE tubing (including PTFE/FEP composite braided series) for the automotive industry is a high-performance tubing that combines the core characteristics of polytetrafluoroethylene with a high-strength braided reinforcement layer. It features a wide temperature range of -60℃ to 260℃, extremely low expansion rate, oil and corrosion resistance, and high pressure resistance. It is widely applicable to brake systems, engine compartments, fuel lines, and other applications. Especially in the brake fluid line field, it meets stringent industry standards such as FMVSS 106, making it a core upgrade component for improving automotive braking safety and extending the service life of tubing.
Disadvantages and Weaknesses of Traditional Piping in the Automotive Industry
High expansion rate of brake fluid lines, leading to delayed braking response.
01
Poor aging and corrosion resistance, resulting in short service life.
02
Insufficient mechanical strength, limiting applicable scenarios.
03
Poor compatibility with brake fluid, leading to rapid performance degradation.

The Revolutionary Impact and Advantages of PTFE Tubing in the Automotive Industry
PTFE brake fluid lines adopt a "PTFE inner tube + 304/316 stainless steel braided layer" composite structure. At a working pressure of 4000 PSI, the expansion rate is as low as 0.000295 cc/ft, a negligible expansion that allows for instantaneous transmission of brake fluid, eliminating pedal play, shortening emergency braking distance, and significantly improving braking sensitivity and controllability, meeting the needs of high-performance vehicles and the aftermarket.
The PTFE inner tube is chemically inert to brake fluid, engine oil, salt spray, and ozone, and can withstand extreme conditions from -60℃ to 260℃. It passes FMVSS 106 salt spray, ozone, and low-temperature bending tests, eliminating the risk of aging and cracking during long-term use. Its service life is more than 5 times that of traditional rubber brake fluid lines, preventing brake line leakage from the source.
The stainless steel braided reinforced Teflon hose has a burst pressure of over 5000 PSI, far exceeding traditional hoses, and can adapt to the high-pressure working conditions of braking systems in various vehicle types, including passenger cars, off-road vehicles, and performance-modified cars. At the same time, its bending radius is only 5-8 times the pipe diameter, facilitating installation in complex chassis spaces and preventing friction and interference with vehicle components.
The Teflon material is perfectly compatible with various brake fluids, with no swelling or impurity precipitation after long-term contact. This prevents wear on brake system valves and pipe blockages, reducing the frequency of brake system maintenance. Its non-stick surface prevents oil and dirt buildup, making cleaning easy and significantly reducing the total cost of ownership over the vehicle's lifespan.
In addition to brake lines, Teflon hoses can be widely used in engine cooling systems, fuel lines, and wiring harness protection, offering advantages in insulation, temperature resistance, and lightweight design. In the field of new energy vehicles, it can be adapted to battery pack cooling lines and high-voltage wiring harness protection, providing core support for the upgrade of automobiles towards high performance, lightweight design, and extended range, thanks to its low friction and anti-aging properties.
