It is recommended that all systems be clearly labeled with the media being conveyed. For further information please consult Viega Technical Services.
2
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.
3
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 (24 hours) 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.
6
Compliant with CSA 6.32 / ANSI LC-4.
7
All copper or copper alloy components that are exposed in ammonia environments require lacquer or paint coating.
8
HNBR sealing elements are not recommended for silicone based oils.
9
It is a Viega engineering best practice that for heating applications using EPDM, where the media will be running continuously, non-stop at 200°F or above, to consider switching to an FKM sealing element.
10
MegaPressG 󶈵ttings with HNBR sealing elements are compliant with standard UL 180 for combustible liquid applications.
11
Tubing with oxygen barrier should be used for systems with ferrous components.
Viega ProPress and MegaPress systems are
approved for over 2,500 applications. For
information on additional applications to those
listed, please contact [e-mail].
