Location - Interphex Philadelphia, April 2008. Aflex Hose again took its world leading PTFE product range to one of the world’s premier Pharmaceutical and Chemical exhibitions. The Aflex range was led by our flagship product Bioflex a true smoothbore flexible PTFE hose along with our sister products Corroflon, Pharmaline and Pharmalex and were joined by the world launch of Relink our reusable self assembled end fitting range, which is designed to compliment our range of PTFE hoses. Relink - a reusable coupling of the future available today!

At the exhibition, the Relink fitting was partnered to our Pharmalex range of hoses - a PTFE liner with clear outer silicone cover, the hose itself carries FDA certification for all materials, USP Class VI for assembled hose and Atex approval, add to this full certification including CE Marking and 3.1 Traceability and you have a natural successor to the shortfalls of silicone.

Interphex 2008 broke all records for Aflex with a record number of visitors attending our stand. Our experienced engineers held meetings with many of the world’s leading Pharmaceutical and Chemical companies and again showed our extensive PTFE hose range can answer any process or engineering issues and problems that were asked of it.

The Aflex stand was visited by engineers from Amgen, Pfizer, GSK, Novartis, Wyeth, BMS and many others, some with questions, others simply to see the PTFE hose range that is proving to the world that engineering excellence and quality are still available in today’s world of cheaper and inferior alternatives - quality will always prevail.

A member of what is considered to be the World’s Number One Pharmaceutical company made the following statement: "never had we considered that a hose could take into account the rigors of todays processes, answer all the certification and safety issues and show a cost saving of over 50% based on 12-month usage", Today this company would not consider any other hoses.

One question that is always asked surrounds hose management and testing. There are passive RFID systems on the market, there are barcode systems, all based around existing technology, all requiring extreme close proximity reading. A joint venture between a renowned computer design house and the Aflex technology team allowed Aflex to launch FLOWTAG in Philadelphia. FLOWTAG is an active RFID system, readable from 100 mtrs (300 ft) and with Atex approval.

Aflex prides itself on listening to its customer base, considering its issues and designing products to answer its requirements. All products carry a 24-MONTH MANUFACTURERS WARRANTY and have the full support and back up of the Aflex distribution and assembly units based around the world.

AFLEX HOSE, THE BIRTHPLACE OF THE KING OF HOSES.

These designs of end fittings are used in applications where the end fitting material is not compatible with the fluid passing through the hose, so all internal 'wetted' parts must be protected by a chemically compatible plastic.

The difference between PFA Encapsulated hose end fittings and 'Integral PTFE Lined' hose end fittings is clearly defined:

The severely reduced bore size of the PFA Encapsulated fitting design reduces the fluid flow rates through hose assemblies by up to 75%.

Integral PTFE lined fittings have no bore size reduction, so full-bore flow through the hose assembly is maintained.

This means that the time taken to fill or empty vessels through the assemblies can be considerably reduced by choosing a BIOFLEX or CORROFLON assembly with integral PTFE lined fittings.

The internal design of the PFA Encapsulated fitting also creates a significant entrapment zone behind the inserted end fitting tail.

This makes it difficult during cleaning through to ensure the hose assembly has been cleaned out 100%.

Also, in pharma and food applications the entrapment zone which is created by the PFA Encapsulated fitting design can trap products to provide a bacterial breeding area in some applications.

These problems are completely eliminated by the choice of BIOFLEX or CORROFLON hose assemblies with integral PTFE lined end fittings.

AFLEX HOSE PRODUCTS - BETTER BY DESIGN

Aflex Hose today launch Flowtag, an RFID system tailor made to suit the exacting demands of the Pharmaceutical, Biotech, Chemical and Food industries.

Nothing at all, in many cases. Silicone hose and tube is widely and successfully used to transfer chemicals, foodstuffs, and other fluids in a wide range of applications but sometimes problems occur, because there are a number of specific disadvantages which render silicone hose unsuitable in some applications.

Firstly, chemical resistance. Although silicone rubber hose has excellent chemical resistance to nearly all foodstuffs and biological fluids, there are many chemicals, solvents, fuels and oils which interact with silicone rubber, swelling or degrading the rubber and/or contaminating the fluid being transferred.

Secondly, steam resistance. The resistance to steam, especially at steam pressures above 50 psi (3 bar) is limited, as the silicone rubber will degrade with increasing exposure. This represents a problem in applications where steam sterilisation is applied.

Fortunately, there are now alternative products which will solve these problems, yet continue to offer the other advantages which silicone hose provides.

PHARMALINE and PHARMALEX hose products from Aflex Hose include a unique and patented super-flexible PTFE hose liner tube, replacing the silicone rubber liner used in conventional silicone hose construction. The external cover is platinum cured silicone rubber, and the Pharmaline also includes an SS wire braid between liner and cover.

Pharmaline and Pharmalex can do everything that a silicone rubber hose and tube can do, and much more. They meet USP class 6, are made from FDA approved materials, and meet all the other specification requirements, but have much better steam resistance, and almost universal chemical resistance to transferred fluids due to the PTFE liner.

So, if you have a problem with your silicone hose, or would like a product which provides greater reliability and a longer service life, read more about Pharmaline and Pharmalex, on this website.

Please remember to include your personal details and an address to which the samples will be sent.

Please do not hesitate to contact your Engineer or Distributor to discuss these or other products from our range.

Corroflon and Bioflex are well known products in Pharma and Biotech applications, but are now being increasingly used as a Chemical Hose in Chemical Plants around the world.

The primary reason is the fact that when used in the many chemical hose applications, where corrosion resistance is specifically required, the PTFE hose lining provides the ultimate corrosion resistant hose product.

This thick wall PTFE lining is also extended through the bore of the end fittings, then flared to form the sealing face, isolating and protecting the end fitting from the corrosive fluid passing through.

In Chemical Hose applications, another benefit of the PTFE hose lining is that the media passing through will not be subject to any contamination from chemical reaction with the hose lining - often a problem with conventional chemical hose products which have non-PTFE hose lining, and which are not able to provide the excellent resistance to chemical reactions which is ensured by using PTFE.

Other PTFE and FEP lined chemical hose products are available from other suppliers, but experience over time has shown that the thinner wall section, poorly processed PTFE and hose design faults have often led to premature failure, leading customers to switch to the tried and proven Corroflon and Bioflex products from Aflex Hose.

Whether being used as an acid resistant hose, or for general chemical resistance against alkaline solution or corrosive media like chlorine or sodium hydrochloride, Corroflon or Bioflex are chemical resistant hose products, which can be relied upon to perform successfully and reliably.

PTFE Beaded Triclover Fittings for BioPharm Hose applications

Yet another new end fitting design from Aflex Hose, developed in response to customer requests.

Several of our BioPharm Hose customers were using triclover connections with PTFE triclover 'envelope' gaskets, to avoid contact between the fluid passing through, and the rubber used in conventional gaskets.

These gaskets are difficult to use, fail prematurely, and do not always form a reliable seal.

Aflex Hose have responded with the PTFE Beaded Triclover Fitting.

This design prevents fluid contact with both the steel fitting and any rubber component, and permits full-bore fluid flow through the joint without any crevices. The seal is reliable, and long lasting.

Please view our Bioflex PTFE hose product literature on this website, which includes a more detailed description of this unique, patented fitting design.
