AFlex Hose's Bioflex - Rubber Covered Hoses |
|
|
|
|
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 cleanability 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 colors 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. |

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 vulcanized 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 color 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 to 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 vulcanized directly onto the braid.
Limitations -
Available in lengths up to 10 meters.
