The type Y16/Y19 seals are an all metal narrow section, edge welded bellows seals for very high temperature application especially in refineries or industrial heat transfer media.

The seal incorporates state of the art bellows design proven in many thousands of applications around the world. The benefits of Eagle edge welded metal bellows seals for high temperature application are:

Salient features:

• Complete resistance to temperatures to 425^o C without cooling.
  
• Superior face tracking reduces leakage and "coking".
  
• Special bellows design minimises variation in face load due to shaft expansion or face wear.
• Resistant to Abrasive particles in pumpage, no shaft/sleeve fretting.
  

Variations of metallurgy and face material options make the Y19 suitable for a wide variety of applications in the Refining, petrochemical and chemical industry as well as in other industries where secure sealing under extreme temperature conditions is necessary.

Special EPIL vibration dampeners in Y16 absorbs shaft variation while extending seal life. Pressure capability of the standard seal can be enhanced through the use of a double ply version designated as Y66 and Y99 seals.
