TUBING/HOSES
How to Select Pneumatic Tubing?
Based on Routing Requirements, Operating Conditions, and Applications
Role of Pneumatic Tubing in Compressed Air Equipment
Pneumatic tubing is used to convey compressed air and connect air sources to various pneumatic components.
Tubing may be required to move with machine operation or remain in fixed routing configurations.
Different routing requirements and operating conditions correspond to different tubing selections.
In practical selection, common questions include:
• How to select pneumatic tubing?
• What are the differences between tubing types?
• Should selection be based on routing requirements or operating conditions?
Classification Criteria for Pneumatic Tubing
In practical applications, pneumatic tubing is primarily classified based on routing requirements, application types, and operating conditions.
By Routing Requirement
Whether the tubing needs to move is one of the fundamental criteria in tubing selection.
● Dynamic routing
● Fixed or semi-fixed routing
● Retractable routing
By Application
Tubing usage varies depending on application type.
● General pneumatic equipment
● Air brake applications
● Air supply for tools and operations
By Operating Conditions
Tubing selection also varies under different operating conditions.
● Higher working pressure
● Exposure to sparks or heat sources
● Low-temperature or outdoor use
● Low-pressure fluid transfer
Tubing Types and Selection Criteria
| Tubing | Routing Requirement | Operating Conditions |
|---|---|---|
| PU Tubing | Dynamic routing | Frequent bending or movement |
| Nylon Tubing | Fixed or semi-fixed routing | Long-distance and stable conveyance |
| LDPE Tubing | Low-pressure routing | Low-pressure fluid transfer |
| Reinforced PU Air Hose | High-pressure routing | Higher working pressure |
| Hybrid Air Hose | General-purpose routing | Low-temperature or outdoor use |
| Anti-Spark Tubing | Special environments | Exposure to sparks or heat sources |
| Coiled Air Hose | Retractable routing | Space-saving and flexible operation |
| Air Brake Tubing | Vehicle-fixed routing | Compliance with FMVSS 106 (DOT) |
| Coiled Air Brake Hose | Vehicle dynamic connection | Connection between tractor and trailer |
Tubing selection is not determined by a single factor. It should be evaluated based on media, working pressure, and operating conditions to align with system requirements and routing configurations.
