A flange for a pressure vessel includes a rim, a sealing seat, and an undercut fillet. The rim has an annular surface for abutting an annular end of a cylindrical wall of the pressure vessel. The sealing seat has a cylindrical surface for abutting an inner surface of the cylindrical wall of the pressure vessel nearby the annular end. The undercut fillet is disposed between the rim and the sealing seat. A concave surface of the undercut fillet extends the annular surface of the rim radially inward and then curves back outward to intersect the cylindrical surface of the sealing seat. The undercut fillet of the flange helps distribute stress produced from a pressure differential between the inside and outside of the pressure vessel.
