 Figure 3-2 of the Kalsi Seals Handbook, Rev. 1 has the recommended gland details.  Gland width recommendations are based on low differential-pressure testing, and finite element analysis of nominal dimension seals at 350ºF (176.7ºC) having a conservatively estimated coefficient of thermal expansion of 13E-5 in/in/ºF. MMC seal tolerance conditions were not considered because it was considered unlikely that a seal would be at the upper bound of both the thermal expansion range and the dimensional tolerance range. For detailed seal width predictions as a function of tolerance conditions and seal diameter, see Appendix C. The recommended gland widths that are included in the table above were developed to minimize seal to gland clearance to inhibit skew-induced wear of seals in low differential pressure applications, and do not take media-related swelling into account. Increased gland width may be desirable if significant swelling is anticipated; see Section 3.4. Since the gland widths in the table above may result in axial confinement of the seal at high temperature; it may be beneficial to increase the gland width to accommodate the thermally-expanded width of the seal in high differential pressure applications, in order to achieve reduced interfacial contact pressure. Such gland widths can be based on the seal width predictions in Appendix C.
