Chesterton 4400 Dual Concentric Gas Seal

Product by: A.W. Chesterton Company

Accommodates Loss of Barrier Gas for Greater Sealing Reliability

​Chesterton has developed technology that makes the use of a gas seal easy and intuitive. The 4400 delivers higher reliability with lower gas consumption than conventional gas-lubricated seals.

  • Transitions to a traditional liquid seal in the event of the loss of barrier gas and recover to a gas seal upon restoring the barrier gas
  • Compact flush mount design that does not require modification of the stuffing box; fits more equipment types than conventional gas seals
  • Innovative in-Gland Control System (IGCS) dynamically controls gas pressure to process pressure​
