Clearance is determined by pressure and durometer.  See the chart  Also, consider temperature range variations.
Reduce Clearance 50% when using Silicone or Fluorosilicone.
Glad Depth can be increased up to 5% when using Back-Ups for ease of installation.
Note: The above chart and information is intended for reference use only.  
Gland design has many variables to consider such as temperature, pressure, range, performance requirements..
