摘要

A coaxial hose for electrostatic oiling systems that includes a flexible external tube, and a flexible internal tube for the circulation of a second fluid inside thereof. The internal tube together with the external tube form an annular space for the circulation of a first fluid. The internal tube includes an internal layer made of PTFE that is intended to contain the second fluid, internal braiding that is intended to lend the internal tube pressure resistance and an external layer that is made of polyamide material which is intended to prevent the passage of the first fluid through the braiding.
