The introduction of Bioflex hose in 1998 was the most important advance in PTFE hose design to take place in the last 20 years. There had been a long-recognised need for a PTFE lined hose with the flexibility of a convoluted hose, but with a smooth bore. The smooth bore was requested for two main reasons: firstly, for inner cleanability, in order to avoid fluids being trapped in the convolutions; and secondly, to overcome the turbulent flow induced in convoluted hose bores, which severely reduces the flow rates through the hose. The key feature of Bioflex PTFE hose is the PTFE liner tube design, comprising integral rib sections which support the tube against kinking, vacuum and pressure, and highly compressed web sections which give a smooth bore inner surface and excellent flexibility. 
Another feature is the integral PTFE lined and flared end fitting design which is available for all standard end fittings applied to Bioflex hose assemblies. This provides clean, full-bore flow through the end fitting without any restrictions or entrapment points - unlike conventional fittings, which introduce a bore restriction, also an entrapment crevice at the inside end of the fitting tail. Much higher flow rates are achieved, in comparison with conventional fitings, reducing the time required to fill/empty vessels through the hose. Bioflex has become the established standard in high purity process fluid applications all over the world, and continues to be introduced into new applications every day. SIZE RANGE: 3/8" (9.5mm) up to 2" (50mm) HOSE DESIGN OPTIONS: Natural or anti-static PTFE, stainless steel braid, with or without an EPDM or silicone rubber cover, or polypropylene, PVDF or hastelloy braid. END FITTING OPTIONS: ASA150 or DIN flanges, Sanitary Triclamps (Triclovers), Camlocks, DIN11851, RJT, RJP and SMS fittings, BSPT or NPT fixed males, BSP or NPSM females, JIC, I-Line and many other standard and special fitting designs.
NOTE: The bore size of the hose is maintained right through the end fitting. ADVANTAGES: No bore restriction at the ends, as with conventional inserted fittings, therefore higher flow rates. Free, cleaner flow of fluid, without the fluid entrapment which occurs at the inside end of an inserted fitting.
