It is recommended that all systems be clearly labeled with the media being conveyed. For further information please consult Viega
Technical Services.

All Viega systems must be used with the manufacturer's recommended sealing element.
Contact your local Viega representative or Viega Technical Services for speci󶈵c application temperature, pressure, and concentration limits.

System pressure and temperature ranges depend on sealing element. Any ranges listed above will be overruled by the sealing element
limits here:
3a
EPDM temperature ranges are typically 0°F to 250°F.
3b
FKM temperature ranges are typically 14°F to 284°F with temperature spikes (24hr) up to 356°F.
3c
HNBR temperature ranges are typically -40°F to 180°F.
4
System must contain adequate condensate drainage.
5
Ambient temperatures should be taken as normal operating conditions for the applications not to exceed sealing element limitations.

DANGER!
Failure to verify suitability
Failure to verify suitability of the system for certain
applications may cause serious personal injury or even death.
■ It is the responsibility of designers to verify the suitability of type
304 or 316 stainless steel tubing for use with intended 󶈶uid media.
■ The 󶈶uid's chemical composition, pH level, operation temperature,
chloride level, oxygen level, and 󶈶ow rate and their e󶈴ects on AISI
type 304 stainless steel and/or type 316 stainless steel must be
evaluated by the material speci󶈵er to con󶈵rm adequate system life.
The use of the system for applications other than those
listed or outside of these parameters must be approved by
the Viega Technical Services Department.
