Rubber Air Hose
Added Strength with a Rubber Air Hose
In spite of the availability of new raw materials for the assembly of gas tubes and pipes such as polyvinyl chloride and polyurethane, a rubber air hose is still very much favored among those who operate pneumatic tools. It could be made either of natural or synthetic material.
These tubes are often constructed with several plies for better durability thus giving the potential for years of productive use. Some units are equipped with synthetic yarn spiral weave or braided with polyester for more strength. Other forms of reinforcement come in the form of nylon fabric ply with helical steel wire. They are designed for heavy duty use in a range of applications such as agriculture, industry, or construction.
With its added strength, a rubber air hose can handle pressures of up to 250 psi. Others models can even go as high as 300 psi with maximum burst pressure of 1200 psi. It can function within a temperature range of -20° to 200°F.
Some models come with bend restrictors, effectively increasing their bend radius, preventing damage to the tubes. Both the inner tube and the outer cover are oil resistant giving the equipment a clean look.
The most common colors used for these tools are red and black.
