Dual-Braid PTFE Hydraulic Hose for Gas, Oil, Water and Chemical Media

Introduction

A dual-braid PTFE hydraulic hose is designed for fluid systems that require greater pressure resistance than a standard single-layer braided PTFE hose.

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

The PTFE inner tube provides chemical resistance and smooth flow, while the dual stainless steel braid improves working pressure, burst strength and mechanical protection.

This hose is suitable for the hydraulic transmission of gas-based fluids, oil-based fluids, water-based fluids and chemical materials.

What Is a Double-Layer PTFE Braided Hose?

A double-layer PTFE braided hose contains:

• One smooth PTFE inner tube

• Two layers of 304 stainless steel wire braid

The first and second braided layers work together to restrict PTFE tube expansion under pressure.

Compared with a single-braid structure, the dual-braid design generally provides:

• Higher pressure capability

• Greater burst resistance

• Improved hose stability

• Better resistance to pressure pulsation

• Additional mechanical protection

Why Use a Dual-Braid PTFE Hose?

Industrial hydraulic and process systems may experience pressure variation, vibration and exposure to different fluids.

An unsuitable hose can suffer from:

• Excessive expansion

• Chemical degradation

• Pressure fatigue

• Cracking

• Fitting leakage

• Premature failure

• Reduced service life

The dual-braid PTFE hose provides a reinforced solution while maintaining the chemical compatibility and temperature resistance of PTFE.

Key Features

Two Layers of 304 Stainless Steel Braid
