Double Stainless Steel Braided PTFE Hose for Hydraulic Fluid Systems

Introduction

A double-layer PTFE braided hose is designed for hydraulic and industrial systems requiring higher pressure resistance than a conventional single-braid PTFE hose.

The JCC-01200-PTFE series uses a smooth PTFE material-contact inner tube covered by two layers of high-strength 304 stainless steel braided wire.

The PTFE inner tube provides chemical resistance and a low-friction flow path, while the double stainless steel reinforcement helps increase working pressure, burst strength and mechanical stability.

This hose is suitable for hydraulic transmission involving gas-based fluids, oil-based fluids, water-based fluids and compatible chemical raw materials.

Product Construction

Smooth PTFE Inner Tube

The material-contact layer provides:

• Strong chemical stability

• A smooth flow surface

• Low friction

• Reduced fluid retention

• High- and low-temperature performance

First Stainless Steel Braid

The first reinforcement layer helps control PTFE tube expansion and increases pressure capability.

Second Stainless Steel Braid

The second braid provides additional reinforcement, improving:

• Working-pressure resistance

• Burst pressure

• Pressure-pulsation stability

• Mechanical protection

• Hose assembly strength

Single-Braid vs. Double-Braid PTFE Hose

A single-braid hose may be sufficient for many standard-pressure systems.

A double-braid construction is more appropriate when the application requires:

• Higher working pressure

• Greater burst resistance

• Reduced tube expansion

• Frequent pressure fluctuation

• Additional mechanical reinforcement

• More demanding hydraulic operation

The final selection should be based on the complete working conditions rather than braid quantity alone.

Key Features

Two Layers of 304 Stainless Steel Reinforcement

The dual-braid structure provides greater reinforcement than a conventional single-braid design.

Working Pressure up to 40 MPa

The listed 1/4" specification provides a reference working pressure of 40 MPa.

Wide Temperature Range

The catalog operating range is:

-70°C to +260°C

Smooth Internal Bore

The smooth inner surface helps maintain stable fluid flow and reduces internal resistance.

Multiple Fluid Categories

The catalog lists applications involving:

• Gas-based fluids

• Oil-based fluids

• Water-based fluids

• Chemical raw materials

Exact material compatibility must be confirmed before production.
