PU tube (polyurethane tube) and PA tube (nylon tube) are widely used in various pneumatic systems to transmit air pressure. They are not the most important part of a pneumatic system, but they are indispensable. Without PU pipes and PA pipes, various pneumatic components are like scattered pearls and cannot complete the work of the automation system. EMC Pneumatics provides high-quality, high-precision, flexible, and exquisite-looking polyurethane and nylon tubes for pneumatic systems.
