Stainless steel wire reinforced silicone hose

ROMY-FLEX Bright is a Silicone suction and supply hose reinforced with a stainless steel wire. Designed for the biotechnological and pharma industry.

The ROMY-FLEX Bright is a durable, heavy-duty and slightly translucent silicone hose. The high temperature resistant plies and stainless steel wire ensure that the hose is suitable for vacuum applications. The Bright has good resistance to pressure and kinks, but is less flexible. Designed for the biotechnological, medical and pharmaceutical industry where high purity is a must.

Ideal hose for applications with vacuum, gases or fluids

The Bright is ideal for applications with vacuum, gases (CO2, O2, N2 and air) or liquids like water (WFI and demi). The hose can be assembled in the required length and with the required crimp fittings in our own workshop, and can always be delivered from stock.
