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 conditions 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 combinations, contact the Tube Fittings Division.
