The most extreme environments demand an energized sealing solution. Parker’s resilient metallic seals meet the challenges of high temperatures or cryogenics, high pressures, deep vacuum, corrosive chemicals and even intense levels of radiation; performing dependably year after year.
How Metal Seals Work
The seal is compressed in a cavity about 20% on average of its original free height. The force generated through compression of the ring produces a high contact stress at the seal/cavity interface. This force is supplemented by the pressure-energization force which rises in proportion to the increase in differential pressure.
Jacket Materials and Platings
The special alloys and metals used as seal base materials allow the seals to maintain optimum performance at extreme temperatures and pressures for long periods of time.
