Bioflex Ultra


Bioflex Ultra is Aflex’s flagship product for users in the pharmaceutical and biotech industries. The patented PTFE liner design provides a smooth bore (for clean, non-turbulent flow) and a convoluted outer (for flexibility and kink resistance).

In 2013 in response to customer's requests for an even more flexible and kink resistant hose, Aflex re-designed the convolution profile of the Bioflex PTFE liner tube and introduced a high tensile, 316 stainless steel wire, helically wound in to the root of the convolutions. This wire provides greatly increased kink resistance by providing radial reinforcement to the tube, and axial reinforcement to the web section, preventing web section collapse when the tube is heavily flexed.See more.

The actual bore size of the tube and hoses was also slightly increased to permit easier insertion of fittings. Hoses incorporating this PTFE liner tube design have been re-named as .......... BIOFLEX ULTRA. The ultimate PTFE lined flexible hose

Bioflex Ultra 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 Ultra PTFE hose is the PTFE liner design, which comprises integral rib sections which support the tube
