Polyurethane Air Hose
The Light Polyurethane Air Hose Works
A polyurethane air hose is generally lighter than one made of synthetic rubber or even polyvinyl chloride (PVC). It is highly resilient, flexible, and resistant to abrasions, snags, and kinks allowing it to perform well under a variety of harsh conditions. It also resists oil and other chemicals.
Generally, flexible tubes made of this material can withstand up to 250 psi of either gas or water. Braids are usually embedded in the tubes for additional support and reinforcement. Some models use synthetic polyesters for this purpose which are pressed between the outer and inner surfaces of the tubes in such a manner that there is no possibility of separating them from each other.
A polyurethane air hose can withstand extreme temperatures with some models capable of operating at levels ranging from -40 degrees F to 180 degrees F. Even at these levels, it still retains its flexibility. With a bend radius of 2.5 inches, you can easily lay it even in tight corners and U-shaped passages without fear of kinking.
Most models come in bright colors enhancing their visibility, thus preventing the possibility of workers tripping over them. Colors often include yellow, green, blue, orange, and red. Other models are translucent with blue tones with visible supporting braids. Most brands come with reusable fittings that can be joined with a minimum set of tools.
