Metal Tube and Fitting Material Compatibility
Metal Tube and 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 operat-
ing 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.
