PTFE hose with stainless steel increases pressure capabilities
AdvantaPure now offers its stainless steel overbraided PTFE hose in four styles. The hose, called APFOS, provides the purity of PTFE fluoropolymer with the durability and enhanced pressure carrying capabilities of stainless steel. APFOS is used in high-purity industries for critical fluid lines such as pharmaceutical batch, media and buffer transfer, hot and cold food and beverage conveyance and chemical lines.
The four versions include smooth core, convoluted core, silicone-jacketed smooth core and silicone-jacketed convoluted core. It is claimed that the smooth core options offer larger inside diameters than traditional nominal hoses and the maximum amount of flow during fluid transfer. The convoluted core styles are said to offer more hose flexibility and are less susceptible to stress cracking than metal counterparts. Both smooth and convoluted types are available with a layer of platinum-cured silicone over the stainless steel braid, offering two benefits: the silicone supplies heat protection, making the hose better able to withstand harsh environments and easier to handle in high temperature applications, and it provides a wipe-clean smooth exterior to eliminate particle entrapment within the braid wires.
The cores of APFOS are manufactured from virgin PTFE fluoropolymer that is USP Class VI compliant and meets FDA 21 CFR 177.1550 and ISO 10993 sections 5, 6, 10 and 11. The cores are inert and aim to offer long flexural life, low permeability, non-flammability and the lowest coefficient of friction of any solid material. Overbraid material of 304 stainless steel wire permits higher pressure uses, improves flexibility, reduces kinking, and protects the core. APFOS handles temperatures ranging from -73 to 232˚C.
APFOS sizes range from 1/4 through 3” nominal I.D., depending on style. Custom options include conductive black PTFE, hose assemblies with crimped-on ends and identification solutions such as the AdvantaLabel silicone label attachment system. Rubber-covered FEP fluoropolymer hose is stocked as well.
