PTFE Hoses and Fittings


PTFE (Polytetrafluoroethylene) is comprised of a long chain of carbon atoms each linked to two fluorine atoms. The fluorine atoms from a helical spiral that surrounds the carbon chain which protects it. It is this structure that gives PTFE Hoses their excellent properties, including:

Excellent Chemical Resistant High-Pressure Hoses

PTFE is known as the most chemical-resistant material available. Only a very few substances and conditions can affect it, like fluorine gases at a high temperature and high pressure or liquid sodium metal at the boil.

PTFE lined hoses can be used for a wide variety of chemicals, whereas other hose materials may not be chemically resistant, making PTFE the ideal choice for very corrosive chemical applications.

Non-Stick Surface

Using PTFE as a surface for cookware products has shown the world how easy PTFE surfaces are to clean. This means that PTFE lined hoses can be purged 100% clean, more quickly and easier than any other type of hose.

Excellent Temperature Range

The cookware application also shows more of PTFE’s attributes. PTFE itself can be used as a hose liner at temperatures from -150°C up to +260°C, depending upon the hose design and the application conditions. This is the widest temperature range of any rubber or plastic hose lining material.

Buckley Industrial supplies smoothbore and convoluted PTFE hose assemblies. Each has certain advantages and disadvantages, therefore, we also supply a product called Bioflex, which incorporates the smoothbore hose and the convoluted hose.

All hose assemblies supplied by Buckley Industrial comply with the Pressure Equipment Directive (EC/97/23)
