Steel-Wound PTFE Hose for Fuel, Coolant and Lubricant Systems

Introduction

Fluid systems installed on vehicles, hydraulic machinery and mobile equipment face a different set of challenges from stationary factory piping.

The hose may experience:

• Continuous vibration

• Movement

• Temperature change

• Pressure fluctuation

• Fuel or solvent exposure

• Restricted routing space

The JCC-03100-PTFE wire-wound braided hose is designed around these demanding conditions.

Its structure combines a straight PTFE inner tube, one or two layers of copper-plated steel wire winding, and an external 304 stainless steel braid.

This creates a reinforced hose suitable for a range of fuel, coolant, lubricant and chemical-transfer applications.

Why Use a Wire-Wound Reinforcement?

Braided reinforcement and wound reinforcement respond differently to mechanical loads.

The wound middle layer provides circumferential support around the PTFE tube.

This can help:

• Strengthen the hose under internal pressure

• Support the tube structure

• Improve pressure resistance

• Maintain flexible bending performance

• Reduce uncontrolled tube expansion

The external 304 stainless steel braid then adds another layer of mechanical protection.

Lightweight PTFE Inner Tube

The catalog describes the inner PTFE straight tube as:

• Lightweight

• Flexible in bending

This is useful in systems where hose mass and routing are important considerations.

A lightweight flexible line can reduce loads on:

• Fittings

• Supports

• Moving equipment

• Vehicle systems

• Compact installations

Suitable Media

The catalog lists compatible transfer media including:

• Fuel

• Gas

• Strong acids

• Strong alkalis

• Various organic solvents

It also identifies fluid-delivery applications involving:

• Coolants

• Lubricants

• Fuel

Exact chemical compatibility should be confirmed according to actual process conditions.

Applications in Transportation and Machinery

The catalog identifies application areas including:

• Hydraulic machinery

• Trains

• Automobiles

• Ships

• Aircraft

• Rockets

• Spacecraft

• Satellites

These catalog applications demonstrate the intended use across demanding transport and fluid-delivery systems.

For regulated or safety-critical applications, the complete assembly must be evaluated against the required engineering and qualification standards.

Temperature Range

The catalog specifies:

-65°C to +220°C

This range supports both low-temperature environments and elevated-temperature fluid systems.

The maximum operating pressure must be evaluated at the actual working temperature.

Multi-Layer Structure

Why This Hose Is Interesting for Mobile Equipment

Vehicle and mobile systems often need a combination of characteristics:

• High-pressure resistance

• Flexible routing

• Chemical resistance

• Vibration tolerance

• Lower hose weight

• Temperature stability

A hose designed around only one of these requirements may not be enough.

The JCC-03100 structure combines multiple reinforcement methods with a PTFE material path to address several of these issues simultaneously.

Potential Applications

• Fuel delivery pipelines

• Coolant lines

• Lubrication systems

• Hydraulic machinery

• Vehicle fluid systems

• Railway equipment

• Marine pipelines

• Aircraft fluid systems

• Chemical-transfer systems

• High-pressure mobile machinery
