Product Description

Introduction

Selecting tubing for corrosive or high-purity media requires more than checking pressure and diameter.

The tube material must resist chemical attack, remain stable across the operating-temperature range and avoid contaminating the transferred medium.

Ordinary rubber and thermoplastic tubes may swell, harden, crack or release extractable substances when exposed to aggressive chemicals.

Smooth-bore PTFE tubing is widely used where chemical inertness, low friction and a clean flow path are essential.

The JCC-00000-PTFE series is manufactured from PTFE through extrusion, drying, high-temperature sintering and forming processes.

Where Conventional Tubing Can Fail

Chemical-service tubing may be exposed to:

Strong acids
Strong alkalis
Oxidizing agents
Reducing agents
Organic solvents
Temperature variation
Continuous chemical contact
High-purity process requirements

An unsuitable tube may experience:

Material swelling
Surface cracking
Hardening
Chemical decomposition
Permeation
Internal contamination
Reduced service life
Leakage at the connection

PTFE provides a chemically stable alternative for many demanding process conditions.

Smooth Bore and Process Cleanliness

The smooth internal surface of PTFE tubing helps reduce:

Flow resistance
Pressure loss
Material accumulation
Particle trapping
Cleaning time
Cross-contamination

This makes the tubing suitable for applications where the condition of the transferred medium is important.

The low-friction surface also supports stable flow in laboratory, chemical, pharmaceutical and high-purity process systems.

Temperature Performance

The catalog operating range is:

-70°C to +260°C

This wide range allows the tube to operate in both low- and elevated-temperature systems.

However, pressure capability decreases as temperature increases. Working pressure must therefore be evaluated together with:

Actual operating temperature
Tube diameter
Wall thickness
Hose length
Fitting design
Pressure cycles
Installation method

Chemical Compatibility

The catalog lists the tubing for:

Strong acids
Strong alkalis
Strong oxidizing agents
Reducing agents
Organic solvents
High-purity chemicals

Although PTFE resists a broad range of chemicals, the exact medium, concentration, temperature and pressure should still be confirmed before selection.

Typical Application Areas

Chemical processing
Laboratory equipment

When to Select Smooth PTFE Tubing

Smooth-bore PTFE tubing is generally appropriate when the application prioritizes:

Chemical inertness
High-purity media transfer
Low internal friction
Reduced material retention
Easy flushing
Wide temperature resistance
A clean material-contact surface

Applications requiring very tight bends, high external abrasion resistance or high working pressure may require a convoluted or braided PTFE construction instead.
