The steel wire design helps reinforce the strength of the hose to allow for both high pressure and use in suction applications. The hose is capable of maintaining full vacuum at room temperature. The Duda Energy steel wire PVC tubing works excellent in many fluid applications where general chemical resistivity and high pressure handling is required. For industrial use only. This PVC tubing may not be used with food products or drinking applications.
