Max. temperature
of the fluid Fitting in stainless steel, brass, PVDF:
a) 100 °C if the ambient temperature ≤ +45 °C
b) 90 °C if the ambient temperature is
between 45 °C and 60 °C
Fitting in PP: 80 °C
Fitting in PVC: 60 °C
Min. fluid
temperature Fitting in stainless steel, brass: -15 °C
Fitting in PP or PVC: +5 °C
Fitting in PVDF: -15 °C
Fluid pressure depends on the fitting material; see the
pressure / temperature diagramme in chap.
