All Bioflex hose assemblies are labelled with the following information:
- Manufacturers Name
- Hose Size and Grade
- Max. Working Pressure
- Unique Serial Number
- Month & Year of Manufacture
- Aflex Hose Telephone Number
- CE Mark (if applicable)
This information is normally laser-etched on to a loose stainless steel ring, mounted on the hose.

In some cases, at the discretion of Aflex Hose, the information may be etched on to a thin stainless steel plate which is clamped to the hose, or on to the end fitting ferrule at one end. This may be necessary for example, if the customer requires additional information which may not fit on to a ring.

Customers may specify which labelling system they require, and may request additional information on the label.

This system is only applicable to the EPDM (RC or FP) or Silicone (SI) rubber covered grades of Corroflon.

A label and/or Colour Code is encapsulated on to the braid by a transparent rubber cover which is integrally vulcanised and fully bonded to the rubber cover on the hose.

Another alternative is an RFID programmable tag, encapsulated in the Rubber (Aflex Hose "Flowtag" system) - consult Aflex Hose for details

Further information is available on the Puretag product information document on this website.

Note: 1/2" size, Colour Code only, no text.

Colour Coding

This system is applicable to all grades of Corroflon hose. A coloured PTFE spiral strip is wound on to the hose.

It can be left loose, or it can be encapsulated under a transparent, heat-shrunk polyolefin sleeve.
