Smooth PTFE Tubes and Pipes


Smooth PTFE Tubes and Pipes

The main properties of the tubes made with fluoropolymers, in particular PTFE, are their excellent chemical resistance, thermal (-70 ° C + 260 ° C), biocompatibility, extremely smooth surface with very low coefficient of friction, good electrical insulation, fire retardant material, and the PTFE antiadherence itself. These properties of the PTFE pipe make it one of the most versatile tubes and with more possibilities of uses, existing in the market.

PFA pipes, in addition to thermal resistance and corrosion, have the property of being very transparent which makes them ideal for applications such as level indicators in aggressive chemicals, etc.

The tubes in FEP have the peculiarity of being heat-weldable with other fluoropolymers, but they have less thermal resistance (maximum + 204 ° C).

We can supply this type of fine PTFE pipe from 0.25mm to 25mm inside diameter. Our PTFE hoses with metallic outer reinforcement, aramid and polyamide can be supplied in complete rolls or as custom parts with bolted ends. On request we can supply custom colored PTFE, PFA and FEP tubes.

We have a wide range of measures in permanent stock of PTFE fine tubing and PTFE hoses.

In corrugated PTFE tubes, the corrugated design allows them to have a low bend radius and make them one of the most versatile tubes in their application on the market.

We have corrugated PTFE, FEP or PFA tubing in standard thickness from 8mm (5/16 ") to 100mm (4") of inner diameter, and in thin wall thickness we can supply from 20mm (3 / 4 ") up to 50mm (2") of inner diameter.

We can make smooth or walled finishes, As with fittings coated with the same inner tube to avoid contact of the fluids with the fittings. Our PTFE corrugated hoses with metallic outer reinforcement, aramid or polyamide can be supplied in complete rolls or as custom parts with bolted ends.

As we indicated in the table, we have a wide range of dimensions in permanent stock of fine PTFE tubing and PTFE hoses, the figures shown update the actual stock every 5 minutes. If you click on the stock, the quantity is updated instantly.
