The World's Leading Manufacturer of PTFE Flexible Hose

Aflex Hose pioneered the concept of PTFE lined flexible hose for the transfer of process fluids more than 30 years ago.

Corroflon convoluted bore and Bioflex, Corroline and Pharmaline smoothbore hose, all 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 we have continuously developed and expanded our product range to meet increasingly stringent customer demands.

Corroflon - Convoluted, Reinforced PTFE lined Hose

Corroflon was launched in 1978 and, since then, has been continually updated and improved.  Now it is the industry standard convoluted flexible PTFE hose for major chemical, pharmaceutical and food companies worldwide.

The key to Corroflon's success lies in its design and build quality, which guarantees a long, safe and reliable service life.

Corroflon's design differs from every other convoluted PTFE hose on the market, which results in distinctive and measurable performance and safety advantages.

Firstly, Corroflon will give better cleanability and drainability than other convoluted PTFE hose on the market.  This is because Corroflon is designed and manufactured in such a way that the angle of the convolutions is extremely shallow -80° to 120°, compared with only 45° to 65° in other convoluted hose designs.

Secondly, Corroflon is the only PTFE lined convoluted hose on the market to be fully kink and vacuum resistant at high pressures and temperatures.  This is because Corroflon's design incorporates a thick section external helical reinforcement wire, which gives the radial support necessary to ensure maximum strength, whilst maintaining optimum flexibility and cleanability.  The helix wire is welded directly to the end fitting at each end, ensuring security of attachment and electrical continuity.

And thirdly, Aflex is the only PTFE hose manufacturer to guarantee a minimum PTFE liner thickness of 1.5mm for hose sizes 1" and above, which ensures sufficient strength to prevent the tube from being internally pressurised from a sine wave shape into an extended square wave shape, which would lead to porosity and eventually premature failure of the tube.  This thick wall liner also minimises permeation and is extended through the end fittings to give an uninterrupted clean flow of fluid through the fitting.
