It covers different types of tubing such as polyurethane, polyethylene, PTFE, nylon, and rubber, detailing their specifications, advantages, and disadvantages. The document assists users in making informed decisions tailored to their specific applications in the pneumatic and other industries.

1. How To Choose Air Tubes?
When you need some air tubes, do you know how to select the best air tube? Choosing tube that works well is not a
trivial matter. Here is a guide for how to choose the best air tube for your application.
Polyurethane Tubing
1. Fluid: Air, water
2. Size: 3~16mm and 1/8"~1/2" for outer diameter
2~12mm and 0.079"~0.33" for inner diameter
3. Standard Length: 200m per roll for 3~6mm,
100m per roll for 8~16mm
3. Working Pressure: 0-150 Psi
4. Operating Temperature: -20~60 Celsius dgree
5. Advantage: High size tolerance
Good flexibility
Environmental friendly
Degradable
Best cold weather performance
Much lighter than rubber
5: Disvantage: Kinks easily
Sticks to itself
Vulnerable to some solvents
6: Application: Pneumatic industry
What matters
Size: The inner diameter will determine the maximum amount of fluid it can carry. The outer diameter will determine
thickness of the tube. And choose metric size or inch size according to your needs.
Length: The tube needs to be as long as long as you need it to be.
Pressure: It determines that how high pressure it can bear when working.
Temperature: It determines that how low temperature and high temperature it can withstand when working.
Material: It determines how flexible the tube is and how long it will last.
Fluid: It determines what the media will flow through the tube.
Size
Generally speaking, the diameter determines its capacity to deliver fluid. The larger the inner diameter is, the more fluid
it can carry. And the gap between inner size and outer size determines the thickness of the tube. One issue to keep in
mind is the volume of air needed by the tool. Some tools need only a small amount of air while others need more, so
you would need a large diameter tube or connect to a machine with more horsepower. But you need to remember that
larger tubes weigh more, which will will affect the handling of your tools.
Length
A 100 meters tube will reach everything you'd ever want to reach, but it would also be much heavier and bulkier
than it needs to be most of the time. Shortly, lighter hoses may be a better option for smaller jobs. At some point
it becomes easier to move the connected machines than it is to move the hose.
Material
The material the hose is composed of will determine its performance. Each material performs differently under
differing circumstances. The air delivery capacity is the same for all these materials. Let's take a look at the
different materials.
PU tube is short for polyurethane tube, which can
be divided into polyester and polyether due to its
difference in material. The polyester is the regular
one and its fluid can only be air. Instead, the fluid of
polyether can be both water and air.

2. The two layers tubing is also called
flame resistant tubing for its high
flame gradeof VW-1.

Nylon Tubing
Remarks: Normally, we produce Nylon tubing of PAL material. But if you need PHLY material and HIPHL material, we can also
manufacture it for you. In comparison with PAL material, HIPHL material is more bearable at low temperature (-60 ℃ ), and PHLY
material plays better performance at low temperature (-60℃ ) and high pressure.
