RC - Rubber Covered

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 cleanability of the hose is of prime importance.

Design

An SS braided hose assembly has a black, antistatic EPDM external rubber cover extruded directly onto the braid to produce a super-smooth surface finish.

EPDM has excellent chemical resistance, and the hose has a temperature range from -40°C, -40°F up to +140°C, +284°F (internal fluid) or +120°C, +248°F (external temperature).

"RC-Blue", a blue EPDM (non-antistatic) rubber cover is also available, with an extruded finish (>50 metres) or a hand-wrapped finish (<50 metres).

In addition, strips with alternative text, colours and titles are available to special order.

SI - Silicone Rubber Covered

Purpose

As for RC hose, but where the hose may be required to withstand temperatures from -73°C, -100°F up to +204°C, +400°F. SI grade hose is semi-transparent, allowing visual monitoring of the braid.

Design

An SS braided hose assembly has an external smooth finish, platinum cured silicone rubber cover extruded (>50 metres) or hand-wrapped (<50 metres), and vulcanised directly onto the braid.

Specifications

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

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 part 6.3 (Fireproof). This specification calls for an 1100°C (2012°F) 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 to special order.

All FP hose covers are hand-wrapped.

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 hand-wrapped and vulcanised directly to the ferrule, and 300mm (12 inch) along the hose from the fitting. This can be done either on an SS braided hose (RC-300) or on a rubber covered hose as a 300mm (12 inch) long double layer of rubber at the end (DRC-300).

The rubber used is normally black, antistatic EPDM, but if the hose is 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 consult Aflex Hose for an alternative "EPR" system. (EPR includes a 300mm (12 inch) length of loose rubber hose jubilee clipped to the ferrule).
