Flexible Convoluted PTFE Hose for Vibration and Equipment Movement

Product Introduction

Industrial equipment is rarely completely motionless.

Pumps generate vibration.

Machine frames expand when heated.

Equipment modules may not align perfectly after installation.

Maintenance can also require components to be removed and reinstalled with small positional differences.

A rigid fluid line transfers these movements directly to fittings and connection points.

The JCC-10000-PTFE convoluted hose provides a much more flexible connection between machine sections while maintaining the chemical resistance of PTFE.

Its corrugated inner and outer structure allows the hose to deform more easily than conventional straight-wall PTFE tubing.

Flexible Connections Can Protect the Rest of the System

A flexible hose does more than make installation easier.

It can also help accommodate limited amounts of:

• Pump vibration

• Thermal expansion

• Assembly tolerance

• Connection misalignment

• Equipment servicing movement

Without enough flexibility, these forces can be transferred directly into:

• Fittings

• Valves

• Pump ports

• Instrument connections

• Rigid pipe sections

Using a flexible PTFE connection can reduce unnecessary mechanical stress in suitable installations.

Why Convolutions Increase Flexibility

The corrugated geometry allows different sections of the hose wall to move as the hose bends.

This makes the structure significantly more flexible than a conventional straight PTFE tube.

The result is useful where a connection must change direction without requiring a large rigid piping loop.

This can simplify installation between:

• Pumps and tanks

• Dosing units

• Mixing equipment

• Filling machinery

• Laboratory instruments

• Chemical-process modules

Suitable for Equipment That Is Frequently Serviced

Some machines require routine maintenance around pumps, filters or dosing modules.

A rigid connection may need to be completely dismantled before components can be moved.

A flexible hose can provide more installation tolerance during:

• Filter replacement

• Pump servicing

• Valve maintenance

• Module removal

• Equipment adjustment

The hose should still be installed within its specified bending limits and should not be treated as an unlimited-motion joint.

PTFE Material Advantages Remain

Despite the more flexible geometry, the material itself remains PTFE.

The catalog lists applications in:

• Pharmaceutical industry

• Food industry

• Chemical industry

PTFE offers broad compatibility with many process fluids, subject to confirmation for the exact application.

Temperature Range

The catalog specifies:

-70°C to +260°C

This allows the hose to function across a broad range of equipment temperatures.

Pressure capability should be evaluated according to the actual operating temperature and hose size.

Typical Equipment Applications

• Pump flexible connections

• Chemical dosing equipment

• Pharmaceutical machinery

• Food-processing systems

• Laboratory instruments

• Mixing equipment

• Filling machinery

• Process skids

• Vibration-sensitive connections

• Customized fluid-handling machines

Why This Is Not Just a “Small Bend Hose”

A convoluted hose is often selected because it bends easily.

But its value can go beyond space saving.

It can also act as a flexible transition between two machine sections that do not remain perfectly fixed relative to each other.

That makes it particularly useful in equipment involving:

• Vibration

• Thermal cycling

• Maintenance movement

• Alignment variation
