About PTFE hoses

PTFE hose is used where temperature or medium is too much for an ordinary plastic hose. The material resists most aggressive media, slides very well and has an extremely low coefficient of friction. The temperature range runs from -60 °C to 260 °C.

What matters when choosing

• Hose diameter: six sizes from 4x2 to 12x9, given as outside by inside diameter in mm. The bore sets the flow, the wall thickness the pressure rating.
• Operating pressure at 20 °C: figures range from 42 bar for 4x2 down to 14 bar for 10x8. Size and permissible pressure therefore have to be considered together.
• Temperature range: -60 °C to 260 °C. One and the same line covers heated sections as well as low temperature applications.
• Reel length: supplied on 50 m reels. For short runs the offcut has to be allowed for.
• Colour: the whole group is natural. Colour coding of lines has to be done by marking rather than by the hose itself.

Typical applications

• Hot media in drying and heat treatment plants
• Dosing and sampling lines for aggressive liquids
• Food and filling plants with corresponding requirements on the line
• Laboratory and process engineering with changing media
• Routing close to heat sources where ordinary plastic hose ages

According to the product text the hose meets the requirements of the food regulation, it is supplied in natural colour on 50 m reels. Production is in Italy.
