PTFE hose reinforced with stainless steel wire and silicone cover

ROMY-FLEX PTFE SIL is a PTFE suction and supply hose reinforced with a stainless steel wire, ideal for CIP, negative pressure or aggresive media. 

The ROMY-FLEX PTFE SIL is a durable and heavy-duty hose which is resistant to high temperatures and mechanical stress. The PTFE SIL is reinforced with a stainless steel wire, like the ROMY-FLEX Bright, enabling under pressure and suction. The hose is completed with a white Silicone cover. Designed for the biotechnological, medical and pharmaceutical industry where high purity is a must.

Ideal hose for applications with aggressive media, CIP or negative pressure

The PTFE SIL is very suitable for CIP applications and can be used all-round for processes with aggresive media and vacuum. 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.
