    • Et al.


How it works

How it Works

  • Acts like a large scale compression fitting

  • Stuffing is trapped behind a removable gland

  • Leaks a few drops per minute while the shaft is turning

  • 10 psi lubricant can be used if the process fluid is abrasive


Operating conditions

Operating Conditions

  • Flax stuffing boxes are used to hold steam inside the cylinder of a steam engine

  • More extreme conditions would require more high-tech stuffing material

  • Oil field stuffing boxes can operate up to 540°F and 3,000 psi
