PTFE Hose/PTFE Spiral Hoses with flanges and wire braid
The PTFE Spiral Hoses with flanges and wire braid can make up for the axial or radial error on installation, and they can solve the problem of expansion and contraction caused by climate change at the same time.
Product specification
The advantages of PTFE Spiral Hoses with flanges and wire braid include large compensation amount, excellent mechanical performance, good corrosion resistance, long service life, etc.
As a vibration damper, it is installed at the inlet and outlet of the pump or both ends of other high-frequency vibration machines to reduce vibration, which can improve the service life and sealing performance of the pipeline.
