Metal wound gasket made of PTFE/304

Depending on pressure and temperature, TPFE gaskets can be used at low pressures; however, when either temperature exceeds 200°C or pressure reaches 1.0 MPa, TPFE is not recommended – in such cases, metal-graphite wound gaskets should be used. For specific selection criteria, refer to the standard HGT 20610-2009: Wound Gaskets for Steel Pipe Flanges (PN Series)

Tetrafluoro. Nowadays, fluids with temperatures not exceeding 180°C can basically be used.
