AdvantaPure recently introduced its stainless-steel-overbraided PTFE hose in six variations. Called APFOS, the hose offers the purity of PTFE fluoropolymer with the durability and enhanced pressure carrying capabilities of stainless steel. APFOS is used for applications in the chemical, food and beverage, pharmaceutical, and other high-purity industries.
APFOS is constructed of a virgin PTFE core overbraided with series 300 stainless steel wire. The core provides non-restrictive flow and an inert surface to transport fluids. APFOS handles temperatures ranging from -65°F to 450°F; -54°C to 232°C.
Stock offerings consist of white or conductive black PTFE fluoropolymer cores in smooth or convoluted styles. Smooth core hose provides maximum flow, while convoluted offers flexibility. Silicone jacketed APFOS (APFOSJ) is available in white core in either smooth or convoluted core (conductive black is available through custom order). The silicone offers a degree of heat protection, making the hose easier to handle in higher temperature applications. It also provides a smooth exterior to eliminate particle entrapment and allows the surface to be wiped cleaned.
APFOS sizes range from 1/4 through 4 nominal I.D., depending on style. Custom options include hose assemblies with crimped-on or flare-through ends, non-stock sizes, special packaging, and identification solutions. Rubber-covered FEP fluoropolymer hose is stocked as well.
