'Tafting' is a process which allows the lining of the hose to be extended through the bore of the end fitting and across the sealing face, in one, continuous length.
The advantage of 'Tafting' is that all wetted parts are lined with 'PTFE' and that there are no joins, overlaps, ridges or week spot inside the hose assembly.
Most fittings with a flat sealing face at 90O to the bore, in sizes 1" or above, are suitable for 'Tafting'.

The pressure capacity of Convoluted 'PTFE' Hose is affected by temperature. A temperature correction factor needs to be applied to the working pressure stated above, when working at temperatures other than 20O C.
Please contact our sales office in these cases.
'PTFE' smooth bore hose is also available with fittings to customer specifications.
