Why it is specified

The parts that are specified last and hold up the build. Held in stock in the common sizes and finishes, so the vessel is not waiting on a four-week lead time for a sight glass.

Typical applications

  • Sampling from a closed vessel
  • Tank cleaning
  • Vessel access for maintenance
  • Vessel inspection and level sighting

Options and executions

  • Electropolished finish with a surface report
  • Integral light fitting
  • Material certificates to EN 10204 3.1
  • Wiper for the window
