Flexible Convoluted PTFE Hose for Compact Process Equipment

Introduction

Space inside modern processing equipment is becoming increasingly limited.

Pumps, valves, filling heads, tanks, sensors and structural frames often leave little room for conventional rigid tubing or large-radius flexible hoses.

In these applications, the fluid line must bend around equipment components while still providing chemical resistance and reliable material transfer.

The JCC-10000-PTFE convoluted PTFE hose uses a corrugated PTFE structure on both the inner and outer walls, giving the hose significantly greater flexibility than conventional smooth-wall PTFE tubing.

It is designed for pharmaceutical, food and chemical equipment where compact routing and frequent changes in hose direction are important.

Why Conventional Smooth PTFE Tubing Can Be Difficult to Install

Smooth PTFE tubing offers excellent chemical resistance, but larger sizes can require relatively large bending radii.

Inside compact machinery, this may create several installation problems:

• Insufficient space for large bends

• Excessive stress on connectors

• Difficulty routing around pumps and valves

• Need for additional elbows

• Increased rigid-pipe connections

• Poor accommodation of machine vibration

• Difficult maintenance access

A convoluted structure allows the hose to change direction over a much shorter distance.

Corrugated Geometry Provides High Flexibility

The JCC-10000-PTFE series uses corrugated PTFE walls rather than a conventional straight-wall structure.

This geometry allows the hose to flex more easily without requiring additional metallic reinforcement.

For example, the catalog lists minimum bending radii of:

• 20 mm for 1/4"

• 22 mm for 5/16"

• 26 mm for 3/8"

• 26 mm for 1/2"

This makes the hose particularly useful in densely packaged processing equipment.

Suitable for Complex Machine Layouts

A highly flexible hose can simplify piping around:

• Pumps

• Metering units

• Filling machines

• Mixing equipment

• Tanks

• Valves

• Instrument panels

• Sampling systems

• Laboratory equipment

• Process skids

Instead of redesigning the equipment around the hose, the hose can be routed according to the actual machine geometry.

PTFE Chemical Resistance

Flexibility does not remove the fundamental advantages of PTFE.

The hose maintains PTFE's compatibility with many industrial process media, subject to final confirmation of temperature, concentration and pressure.

Potential media include:

• Acids

• Alkalis

• Chemical solutions

• Pharmaceutical fluids

• Food-processing materials

• Solvents

• Process liquids

The catalog specifically lists applications in:

Pharmaceutical, food and chemical industries.

Wide Temperature Capability

The catalog temperature range is:

-70°C to +260°C

This broad operating range allows the hose to be considered for:

• Refrigerated process environments

• Ambient-temperature chemical transfer

• Heated production lines

• High-temperature cleaning

• Temperature-sensitive fluid systems

Pressure capability must always be evaluated at the actual operating temperature.

Why Flexibility Matters Beyond Installation

A flexible fluid connection can also help accommodate small amounts of:

• Equipment vibration

• Thermal expansion

• Assembly tolerance

• Alignment variation

• Maintenance movement

This can reduce excessive side loading on fittings when compared with a rigidly constrained connection.

For continuous dynamic movement, however, bending frequency and installation conditions should be evaluated separately.

Typical Applications

The JCC-10000-PTFE series can be considered for:

• Pharmaceutical processing equipment

• Food production machinery

• Chemical transfer systems

• Filling machines

• Dosing equipment

• Laboratory instruments

• Flexible pump connections

• Mixing systems

• Compact process skids

• Sampling equipment

• Fluid handling machinery

• Customized automation equipment

Product Construction

Reference Product Data

These values are catalog reference data. Final working pressure depends on temperature, fittings and complete hose configuration.

Convoluted PTFE vs. Smooth PTFE Tubing

The two structures serve different installation priorities.

Smooth PTFE Tubing

Better suited when the priority is:

• Smooth internal flow

• Low material retention

• Simple straight routing

Convoluted PTFE Hose

Better suited when the priority is:

• Very small bending radius

• Flexible routing

• Compact equipment

• Complex hose paths

• Easier installation around components

The correct structure should therefore be chosen according to both the transferred medium and the physical machine layout.

When Should You Select This Hose?

The JCC-10000 series is a strong option when:

• A normal PTFE tube cannot make the required bend

• Equipment installation space is limited

• The hose must route around multiple components

• Chemical resistance is required

• Temperature conditions vary widely

• A flexible PTFE connection is preferred over rigid tubing
