Some methods of employing a cylinder with a rectangular mount can produce a condition where flexure of the flange can result in fatigue failure of the mounting bolts or flange retainer fasteners. If pressures in excess of those shown in the chart below are anticipated, a more rigid mount such as an FFX, RFX, FHF, or RHF should be selected. Whenever there is doubt, select a FHF or RHF mount.
