PTFE Hose

What is PTFE?

Polytetrafluoroethylene (PTFE), more commonly known as Teflon®, is a plastic resin that was discovered by DuPont researchers in the 1930s. PTFE is used in an array of applications, such as industrial hoses and fluid transfer equipment, where an extreme level of chemical resistance is required.

PTFE Hose

There are two common types of Polytetrafluoroethylene hose, and each one has its own set of qualities that make it worth considering.

Smooth Bore Hose – The smooth bore hose is made for applications that require high flow rates for the transfer of fluids. Typically, smooth bore PTFE hoses come in a diameter that is less than 1 inch, as this helps prevent the hose from kinking while fluids are passing through it. Smooth bore hoses have a higher bend radius than convoluted hoses and this means that they do not have the flexibility that is associated with convoluted hoses. The primary benefit to using a smooth bore hose is its price, which is considerably lower than that of other PTFE hoses.

Convoluted Hose – The convoluted hose is particularly noted for the increased flexibility that it affords over similar hoses. Convoluted PTFE hose is four times more flexible than smooth bore hose of the same diameter which allows it to be used on a wider variety of equipment. In addition to its flexibility characteristics, convoluted PTFE hose has a superior level of resistance to collapse under vacuum than smooth bore hoses, due to the structure of the hose wall.
