Metal Bellows Mechanical Seals (604)

These Metal Bellows Mechanical Seals (604) is the leading seal of choice for demanding, high-temperature applications. Available in either AM350 or Inconel718, Its high-strength design provides maximum reliability. The stationary bellows design accommodates high shaft-to-seal-chamber misalignment.
Unlike rotating seals that must flex on every revolution to accommodate shaft-to-seal-chamber misalignment, the stationary YH604 adapts to this condition by flexing only once during installation. This reduces seal movement, resulting in increased seal life.
