Simple or pre-assembled hoses, in high density polyethylene or in silicone, in classical or reinforced version with an internal braid in aramidic fiber. These articles have an operating range that varies from 80 °C to 250 °C, they are fundamental for the creation of a correct vacuum line as well as for making stable and reliable infusions. They can be used in the most widespread processes for the production of advanced composites such as under vacuum and in high pressure autoclaves. We control sample the different characteristics of any types tube, with maximum temperature of exercise, pressure and vacuum seal. Only in this way is it possible to produce quality products adapted to the whole production process.
