Dual-Reinforced PTFE Hose for High-Pressure Hydraulic Fluid Transfer

Introduction

Hydraulic hose selection becomes more challenging when pressure, temperature and chemical compatibility must all be considered at the same time.

A conventional rubber hydraulic hose may perform well with standard hydraulic oil, but applications involving aggressive chemicals, elevated temperatures or unusual process fluids can require a different material structure.

The JCC-01200-PTFE double-braid hose combines a smooth PTFE inner tube with two layers of high-strength 304 stainless steel braided reinforcement.

The result is a hose designed for fluid systems requiring greater pressure support while maintaining the chemical and temperature characteristics of PTFE.

Why Two Stainless Steel Braids?

The PTFE inner tube provides the material-contact surface, but reinforcement determines how the hose responds to internal pressure.

Adding two braided stainless steel layers helps:

• Restrict PTFE tube expansion

• Increase working-pressure capability

• Improve burst resistance

• Support pressure fluctuations

• Improve mechanical stability

• Protect the PTFE inner tube

• Create a stronger complete hose assembly

This structure can be particularly useful when a single reinforcement layer does not provide sufficient mechanical support for the intended system.

Designed for More Than Conventional Hydraulic Oil

The catalog identifies this series for hydraulic transfer involving:

• Gas-based fluids

• Oil-based fluids

• Water-based fluids

• Chemical raw materials

This broad application range is one of the key advantages of using PTFE as the inner material.

Depending on the exact medium, PTFE can provide strong resistance against many process chemicals while maintaining a smooth internal surface.

Final compatibility should always be confirmed using the actual fluid, concentration, temperature and pressure.

Smooth Bore for Stable Fluid Delivery

The inner PTFE tube has a smooth bore.

This helps reduce:

• Internal flow resistance

• Material retention

• Pressure loss

• Fluid accumulation

• Cleaning difficulty

For hydraulic and process systems, a stable internal passage can support predictable fluid movement between pumps, valves, cylinders and process equipment.

Wide Temperature Capability

The catalog specifies an operating range of:

-70°C to +260°C

This broad temperature window allows the hose to be considered for:

• Cold-process systems

• Standard hydraulic equipment

• Heated chemical transfer

• High-temperature industrial machinery

The actual allowable pressure should be evaluated at the real operating temperature.

Typical Application Areas

Potential applications include:

• Industrial hydraulic systems

• Chemical-process equipment

• Oil-based fluid transfer

• Water-based hydraulic equipment

• Gas-transfer systems

• Temperature-controlled machinery

• Process skids

• Chemical dosing systems

• High-temperature fluid equipment

• Customized OEM machinery

Product Construction

Why This Structure Is Different from Single-Braid PTFE

A single stainless braid is sufficient for many industrial applications.

A double braid becomes more attractive when the equipment requires:

• Higher pressure capability

• Stronger reinforcement

• Better resistance to pressure pulsation

• Reduced hose expansion

• More demanding mechanical performance

The correct selection should depend on the operating conditions rather than simply choosing the hose with the greatest number of reinforcement layers.
