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 "Corroflon 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 Corroflon, AS, SS, RC, DRC-300 hose x 3.00 metres long (10ft).Both ends non-lined ANSI 150# S/S Flanges".

OR by Part Numbers, as defined on the next page.

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

PTFE Liners include, Standard (GP) or Special Purpose (SP), both available either in natural white PTFE or in black, Antistatic PTFE (AS).

There are four types of braid, Grade 304 stainless steel (SS), Polypropylene (PB), Hastelloy (HB), PVDF or Kynar (KYB). Rubber covering and other external protection systems are also available.

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

Note: Most of the sizes of hose and fittings listed in this brochure are available as ex-stock items and are priced accordingly. However, when certain items have not been purchased in the last 12 months, they are no longer held in stock, and are only available to Special Order.

Aflex Hose will advise accordingly when enquiries are placed for these items.

Conditions of Sale

Corroflon hose and hose assemblies are only supplied on the basis that the customer read and accepted the Conditions of Sale as given at the end of this brochure and on the Aflex Hose website.

Selecting the Hose Length

Corroflon hose assemblies are made up to the specific lengths required. The hose length is taken as the length from the sealing face at one end of the hose to the same at the other end. The length tolerance is normally +10% -0% for lengths more than 1 mtr, and +5% -0% for lengths up to 1 mtr. Closer tolerances are available to special order.

* Listed minimum lengths are for the Corroflon Hose only, and DO NOT INCLUDE THE LENGTHS OF THE FITTINGS AT EACH END.

These must be found from the end fitting pages and added to calculate the minimum length of the hose assembly, BUT for Rubber Covered hose grades, RC, FP and SI, the Fitting Lengths are approximately 33% longer than the Fitting Lengths listed, which are for Braided Only Hose End Fittings.

Used straight with fittings in line.

Only minimal vibration permitted.
