Metal Tube & Fitting Material Compatibility
As a general rule, tube and fitting materials should be the
same. If different materials must be considered, the following
chart can be used as a general guide. Since operating condi-
tions differ with applications, this chart should be used only as
a guide and not a firm recommendation. Before making a final
decision on material combination, it should be sufficiently
tested under appropriate conditions to assure suitability for
the intended application. For additional material combina-
tions, contact the Tube Fittings Division.
