Pneumatic tubing
Superthane pneumatic polyurethane tubing allows quick and easy line identification. Designed for air lines, it is naturally flexible for close-in bending — and with no leachable plasticizers used. It resists kinking, abrasion, and temperatures as low as –90°F (–67°C), while it handles working pressures up to 135 psi at ambient temperature. It is more resistant to pressure and vacuum than corresponding sizes of PVC or rubber.
