Bioflex is a smoothbore, highly flexible, PTFE lined hose. Its design overcomes the disadvantages of conventional smoothbore and convoluted PTFE flexible hose designs, dramatically improving on many of their individual technical performance parameters. The key feature of Bioflex PTFE hose is the PTFE liner design, which comprises integral rib sections which support the tube against kinking, vacuum and pressure, and highly compressed web sections which give a smoothbore inner surface and excellent flexibility. Another feature is the integral PTFE lined and flared end fitting design (see next page) which is available for all the standard end fittings on Bioflex Hose Assemblies. This provides clean, full-bore flow through the end fitting without any entrapment points - unlike conventional fittings, which introduce a bore restriction, also a crevice at the end of the fitting tail. This PTFE lining also protects the end fitting from any corrosive media passing through the hose bore. Today, Bioflex has become the established standard in process fluids applications all over the world, and continues to be introduced into new applications every day.

Due to its extremely strong construction, Bioflex has outstanding resistance to temperature and pressure, much higher than that of conventional convoluted PTFE lined hose. All sizes of Bioflex GP,SS and AS, SS are usable at full vacuum up to 130°C. Above this, the vacuum resistance should be reduced 1% for every degree above 130°C. Rubber covered grades the same, BUT ONLY within the temperature limits for the type of rubber. Temperature & MWP Graph for Bioflex GP, SS and AS, SS (Subtracted to calculate Pressure Drop over the Hose Length) Hose with SS Braid as per Graph. Hose with PB Braid, pressure as listed (Page 10) from -30°C to +80°C and 50% less from 80°C to 100°C. Hose with RC, FP and SI grades as per Graph, BUT only within the temperature range for the particular grade of rubber cover, as given below. Bioflex GP is a virgin PTFE liner, manufactured from hose grade PTFE which conforms to the requirements of: FDA 21 CFR 177.1550 Bioflex GP hose liner tube has also been tested, and complieswith: USP Class 6 :

PB -30°C to +100°C
SS,RC & SS, FP -40°C to +140°C
SS, SI -40°C to +180°C
KYB -40°C to +120°C
