RC = Rubber Covered Hoses

Purpose - For the most rugged applications where the hose may be subjected to rough treatment and severe external abrasion. Also for hygienic applications, where the external smoothness and clean ability of the hose is of prime importance.

Design - An SS braided hose assembly has a smooth finish, blue EPDM external rubber cover vulcanized directly onto the braid.  EPDM has excellent chemical resistance, and is temperature resistant up to 120°C (external) 140°C (internal).  Black antistatic EPDM and alternative colours of rubber, and strips with alternative text titles are available to special order.

Alternative types of rubber, such as Hypalon or Nitrile rubber are also available to special order. 

The standard standard blue EPDM rubber has a super smooth finish which is not available for the alternative rubbers.

Specifications - The EPDM rubber cover has been tested and conforms to the requirements of USP Class VI.

RC-300 = Rubber Covered 300mm at End

Purpose  - In applications where excessive flexing of the hose at the end fitting occurs, it is sometimes necessary to 'stiffen' the hose in this area, to prevent kinking.

Design  - A layer of rubber is applied and vulcanised directly to the ferrule and 300mm along the hose from the fitting.  This can only be done with either a SS braided hose (RC-300) or on a rubber covered hose as a 300mm long double layer of rubber at the end (DRC-300).  The rubber used is normally Blue EPDM but if the hose were FP or SI covered, then the same type and colour of rubber would be used (DFP-300 or DSI-300)

Limitations  - Cannot be applied to PB or KYB braided hose.  If required please consult Aflex Hose for an alternative "EPR" system.  (EPR or Ends Protection Rubber) includes a 300mm length of loose rubber hose jubilee clipped to the ferrule.

FP = Fireproof Rubber Covered

Purpose - As for RC hose, but where the hose is also required to resist failure in the event of fire, in accordance with Specification BS5173 Section 103.13 (Fireproof). This specification calls for an 1100°C flame to be applied o the hose at minimum bend radius, maximum operating pressure (water), and one end fitting under vibration. The hose must withstand at least 15 minutes without leakage.

Design -As for RC hose, but the red EPDM rubber is specially compounded to be fire resistant. Black, anti-static EPDM Fireproof rubber is also available as an option.

SI = Silicone Rubber Covered

Purpose - As for RC hose, but where the hose may be required to withstand temperatures up to 180°C. SI grade hose is semi-transparent, allowing visual monitoring of the braid.

Design -An SS braided hose assembly has an external smooth finish silicone rubber cover vulcanised directly onto the braid.

Specifications - The EPDM rubber cover has been tested and conforms to the requirements of USP Class VI.
