PTFE Hose Assemblies

 

FlexTech design & manufacture PTFE flexible hose assemblies to meet the stringent temperature, pressure and vacuum service requirements found in food, pharmaceutical, medical, beverage petrochemical and dairy product applications.
FlexTech PTFE hose and assemblies offer unique properties which include excellent chemical resistance, high temperature resistance  (up to 260°C, 500°F) and a frictionless, easy clean surface.
These properties determine the types of application areas in which PTFE hose can provide the best possible hose product for the job.
Available in PTFE smoothbore or PTFE convoluted bore with assortment grades, covers & end terminations. Compounds manufactured from DuPont in virgin or Anti-Static to FDA 21.CFR.177-1550 compliance.
