The World’s Leading Manufacturer of PTFE Flexible Hose Aflex Hose, founded in 1973, pioneered the concept of PTFE lined flexible hose for the transfer of process fluids more than 30 years ago. Corroflon convoluted PTFE hose and other types of PTFE hose, manufactured and supplied by Aflex, are used by major Chemical, Pharmaceutical and Food companies worldwide. Over the years, hundreds of thousands of custom-built hoses have been designed and built to cope with the most difficult of operating conditions, and Aflex have continuously developed and expanded their product range having pioneered and introduced Antistatic hose, Polypropylene Braided hose and many other innovations in response to customer demands.

In 1998, Aflex fulfilled the most stringent demand yet. Customers, worldwide, had always asked for the ultimate PTFE lined flexible hose... one product which incorporates the advantages of both convoluted and smoothbore designs. A product which is sufficiently flexible, like convoluted, yet which retains the advantages offered by smoothbore, like fast flow rate and cleanability. After years of painstaking research and development, Aflex launched such a hose ... Bioflex. 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.

Conventional convoluted PTFE liner

Bioflex PTFE liner

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 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.
