Swagelok Pressure Gauges

Pressure Gauge Group

Swagelok gauges provide accurate pressure measurement for industrial, ultrahigh-purity, and sanitary applications. They are offered in a wide range of pressure ranges, dial sizes, connections, mountings, and options to support a wide range of customer requirements.

  • Industrial and Process Pressure Gauges
  • Ultrahigh-Purity Pressure Gauges
  • Sanitary Pressure Gauges

Tube Adapter Pressure GaugeSwagelok Tube Adapters Solve Alignment Problems

Swagelok tube adapters can help eliminate difficult alignment problems and can be used with any Swagelok tube fitting. For example, when installing a gauge with a pipe fitting end connection, it is often difficult to align the dial to the desired position without damaging the gauge. However, gauges with integral Swagelok tube adapters eliminate alignment problems.
