Mechanical gauges can be easily attached onto metal vacuum systems, however, due to the construction materials of mechanical gauges, it is often impossible to make a direct seal onto a glass vacuum system. If necessary, a Swagelok or Cajon Ultra-Torr may be used for making a glass-to-metal seal (see Sec. 3.1.5). The glass-to-metal seal may then be fused onto the vacuum system.
