How to Order

How to Order

The quantity, hose size, liner, braid, cover, protection system, length and fittings must be selected and specified in full.

EITHER by a full, written description. The hose grade can be specified by the code initials e.g. “Bioflex Ultra AS, SS, RC, DRC-300” defines an antistatic PTFE lined hose with an EPDM rubber cover over a SS braid, with a double rubber cover at both ends. The quantity, length and fittings can then be written in - e.g. “4 off x 1” bore Bioflex Ultra, AS, SS, RC, DRC-300 hose x 3.00 metres long. Both ends non-lined ANSI 150# S/S Flanges”.

OR by Part Numbers. Example from above “4 off Part No. 16-BFXU/AS-RC-00-3.00m-12-12, with DRC 300 at both ends”.

Any special requirements relating to the hose construction, or information required on Tags, or Certificates, or special testing of requirements, must be specified in full on the enquiry or purchase order.

Selecting the Hose Grade

There are two types of PTFE liner available, natural (GP) and antistatic (AS) and two types of braid; Grade 316 stainless steel (SS) and polypropylene (PB). Rubber covering and other external protection systems are also available.

A hose grade is specified by using the abbreviations given. For example, Bioflex Ultra AS,PB would describe a hose with an antistatic PTFE liner and a polypropylene braid.

Selecting the End Fittings

Bioflex Ultra is available with a range of ‘standard’ end fittings, normally supplied hygienically PTFE lined and flared.

Stainless Steel End Fitting Materials

  • Non-Lined Spigots - are made from Grade 316L SS
  • PTFE Lined Spigots - are made from Grade 316L or Grade 316C SS
  • Cam and Groove Female Fittings - are made from Grade 316C SS (Body) and 316L SS (Spigot)
  • Swivelling Nuts and Flanges - are made from Grade 304 SS
  • Ferrules - most ferrules are made from Grade 304 SS, except some are made from Grade 316L SS - consult Aflex Hose if necessary.

The equivalent specification for the different Grades of Stainless Steel are listed below:

Specification Equivalents List
