Pneumatic tubing withstands moisture, humidity, fungi, and cold temps

April 22, 2009
Polyurethane tubing designed for pneumatic applications is made from hydrolysis-resistant polyurethane to resist attack from moisture. The flexible tubing allows for tight bending in and around equipment, making it a good choice for pneumatic control, robotics, automated machinery, fluid circuitry, lubrication lines, and instrumentation applications. Produced from an ether-based polyurethane compound, the tubing does not contain any plasticizers, which are ingredients used to enhance flexibility, that may leach out and result in flow contamination. The tubing offers cold temperature flexibility to as low as -90°F and virtually unlimited flexural life. The Superthane Pneumatic tubing is a durable product manufactured to resist more pressure or vacuum than corresponding sizes of PVC or rubber. In addition to resisting moisture, it also withstands radiation exposure, kinking, tearing, abrasion, and impact. Available in eight colors plus clear, Superthane Pneumatic tubing makes line identification easy. Large quantities are stocked in 1/16” and 1/8” I.D. sizes. Custom colors, sizes, cut pieces, overbraiding, heat-formed shapes, and thermally-bonded tubing ribbons are available.
