With a registered brand of AiSiLi of Yantai Zhengyuan Polyurethane Co.,Ltd.and made of superior quality of polyurethane,the polyurethane straight air hose also called PU straight air tubes are produced by our advanced equipment and state of art processing technology.Those excellent features include  1）full range and accurate specifications and the tolerance of tube diameters is within 0.05mm; 2) colorful and the color will not fade after long term serving; 3)those transparent tubes are of high degree transparency that the state of the flowing media inside is visible; 4)smaller bending radius to make the linking easier; 5)hardly to be yellowed due to resistant to yellowing reaches above level three; 6)very smooth inside and outside surface and much even tube wall; 7)with standard pressure resistance and long service life; 8)quite capable of resistances to abrasion,pressure,ageing.

The polyurethane straight air tubes apply to transferring the mediums such as compressed air and those liquids without corrosion.PU straight air tubes are used in the fields of vehicle and parts, machinery and components, control and automation, such as pneumatic tools, automation equipment, pneumatic system etc.

Attentions

Be careful to use the tubes for medium of temperature above centigrade degree 60 or corrosive(such as strong acids,strong alkali and solvents with strong polarity etc.),because it may have the risk of tube broken.

Be careful to use the tubes in working places of temperature above centigrade degree 60 or there is chemical gas,because it may cause softening tube leading to significant reduction of pressure resistance or rapid aging and cracking due to corrosion of chemical gas.

Don’t store the tubes in humid warehouse or store them for more than 180days,since it may cause breakage due to hydrolysis.
