PTFE CORRUGATED HOSE

ptfe flex hose

Hose Construction
Helically convoluted inner core made of natural PTFE certified in compliance with RoHS
Directive and U.S. Federal Food and Drug Administration's (FDA) Regulation 21CFR 177.1550.
Premium choice materials and advanced technology guarantee high flexibility and minimum porosiry.
Convoluted inner cores are open picched and self draining.
Outside reinforement:AISI 304L wire braid with high tensile strength.
Options
Customized inner core construction (sizes,thickness and convonlutions pitch).
Inner core made of black antistatic PTFE when electricity resistive fluids are transferred at high flow rates.
Outside reinforcements:AISI 316L-textile braids (e.g. Aramid,polypropylene,polyester).
Additional reinforcements for superior perfomances.
Special jacket made of thermoplastics (e.g. Polyurethane,PA11,PA12,Hytrel,PVC).
Special jacket made of silicone or wrapped rubbers.
Applications
Used globally in low to medium pressure applications which require more flexibility or tighter bend radius.Chemical, petrochemical, paints, inks, glues and adhesives, food stuffs, brake oils, fuels, hydraulic oils, steam, gases, detergents, refrigerants and any application focused on the tranfer of fluids and gases under critical usage conditions and in severe environments.
