duetotheirprotectivechromiumoxidelayer.Thismeans
thatGeberitMapressStainlessSteelisresistantto

•Softened/decarbonisedwater
•Fullydesalinatedwater(deionised,demineralised,
distilledandpurecondensates)
•Ultrapurewaterwithaconductivityof<0.1µS/cm
Resistance against external corrosion
GeberitMapressStainlessSteelisresistanttocorrosion
duetotheatmosphere(ambientair).Theprobability
ofcorrosionisincreasedbycontactwithcorrosion-

Resistance against bimetallic corrosion

Steelisnotinfluencedbythedirectionofflowofthe

metals(gunmetal,copper,brass).
IfGeberitMapressStainlessSteelisdirectlyconnected
togalvanisedsteelpipes,bimetalliccorrosionwilloccur
onthegalvanisedsteelpipes.Thiscanbepreventedby
takingthefollowingmeasures:
• Installationofdistancepieces(lengthL>50mm
surfaceincontactwithwater)
• Installationofashut-offvalvemadeofnon-ferrous
heavymetals.
Colouringcausedbydepositsofothercorrosiveproducts
doesnotindicateanyriskofcorrosion.
Protection against external corrosion

WARNING
Risk of corrosion
Keep cutting tools and deburring tools free
from carbon steel chips when cutting Geberit
Mapress Stainless Steel
Do not use high-speed cutting wheels to cut
the pipe or fittings to length
Only use cutting tools that are suitable for
working with steel
Leaking press connection can be caused by
damaged seal ring
Deburr the outside and inside of the pipe ends
completely
Remove foreign bodies from the seal ring.
Do not tilt the pipe into the pressfitting.
Push the pressfitting onto the pipe, turning the
pipe slightly
Only use lubricants which are free from oil
and grease
