Its composition is a smooth tube in chemically inert fine PTFE and resistant to abrasion. There is a variation in operating pressure with temperature.
Teflon
Ideal for use in laundries as it tolerates thermal cycles and steam applications characterized by frequent on and off cycles, although it is not suitable for use in cold water steam applications.
Its inner tube is made of chemically inert corrugated PTFE, resistant to abrasion. There is a variation in operating pressure with temperature.
