Stainless Steel Braided PTFE Hose | Premium Japanese Material | High-Pressure Chemical Transfer
Engineered for extreme reliability, our SS304 Braided PTFE Hose combines a high-purity Japanese-imported PTFE inner core with a robust SUS304 stainless steel wire braid. This non-standard, customizable hose is designed to handle corrosive chemicals, high-pressure hydraulic fluids, and severe vibrations where conventional rubber or plastic hoses fail.
For sensitive applications, we offer an Anti-Static (Carbon-Black) version to safely dissipate electrostatic charges during high-velocity fluid transfer.
CYLEX supports small-batch customization, offers volume purchasing discounts, ensures rapid delivery, and provides comprehensive after-sales service guarantees.

Key Performance Features
Premium Japanese PTFE Core: Sourced from top-tier Japanese manufacturers for superior molecular density and chemical resistance.
Vibration Resistance: Specially treated joint sections provide exceptional dampening, making it ideal for piping in high-vibration machinery zones.
Extreme Thermal Range: * Continuous: -54°C to +260°C (-65°F to +500°F)
Intermittent: -73°C to +300°C (-100°F to +572°F)
Reinforced Durability: The SUS304 outer braid prevents hose expansion under high pressure and protects against external abrasion.
Fully Customizable: Inner tubes can be swapped for FEP or PFA, and outer braids can be tailored with alternative alloys upon request.
Typical Applications
Chemical Processing: Transport of corrosive acids and aggressive reagents.
Industrial Coating: Precision paint spraying equipment for steel production.
Automotive & Marine: Fuel, lubricant, and hydraulic systems in high-heat environments.
Manufacturing: Plastic extrusion machinery and steam lines.
Frequently Asked Questions (FAQ)
Q: Why use Japanese-imported PTFE for the inner core?
A: Japanese PTFE is globally recognized for its consistency and lower permeability, ensuring a longer service life in high-vacuum or high-pressure chemical applications.
Q: When should I choose the Anti-Static option?
A: If you are conveying non-conductive fluids (like certain fuels or solvents) at high velocities, friction can build up static electricity. Our conductive liner safely bleeds this to the ground.
Q: Can you provide custom end fittings?
A: Yes. Since this is a non-standard product, we can assemble the hose with NPT, JIC, Flange, or Camlock fittings to meet your specific piping layout.
