PTFE inner stainless steel braided hoses are high-performance hosing solutions known for superior chemical resistance and durability, commonly used in automotive, industrial, and chemical processing applications. They offer exceptional temperature and pressure tolerance compared to traditional rubber hoses.
Key Features and Benefits of PTFE Inner Stainless Steel Braided Hoses
Chemical Resistance:
The smooth-bore PTFE (polytetrafluoroethylene) inner liner is inert and provides outstanding resistance to a wide range of fluids, including fuels (such as E85 ethanol blends), oils, hydraulic fluids, brake fluids, and coolants.
Durability and Strength:
The inner core is reinforced with a 304 or 308-grade stainless steel wire braid to provide pressure strength, stability, and excellent abrasion resistance. This construction allows the hose to operate under high pressures and in demanding environments.
Temperature Tolerance:
These hoses can handle a wide temperature range, typically from approximately -70°C to +260°C continuous service (or -94°F to +500°F).
Low Permeability/Vapour-Free:
The PTFE liner ensures a non-stick surface that resists fluid permeation, making it suitable for in-cabin fuel lines as it helps eliminate fuel odours.
Flexibility:
While less flexible than rubber hoses, the braided construction provides a good balance of flexibility and durability, and some versions feature a convoluted core for enhanced flexibility.
Hygienic Properties:
The non-stick, easy-to-clean surface makes these hoses ideal for applications in the food, beverage, and pharmaceutical industries where hygiene is critical.
Typical Applications
PTFE inner stainless steel braided hoses are widely used across various industries:
Automotive/Motorsport:
Performance fuel systems, turbo oil feeds, brake and clutch hydraulic circuits, and power steering systems.
Industrial:
High-pressure gas transfer and general industrial fluid transfer systems.
Chemical Processing:
Transporting aggressive chemicals that would degrade other hose materials.
Food, Beverage, and Pharmaceutical:
Hygienic transfer of sensitive liquids and gases where contamination must be avoided.
Aerospace:
Applications requiring reliability in high-performance and high-temperature environments
