Balanced Hollow Metal O-ring Seal

Short Description:

On the basis of the basic sealing ring, several small holes are drilled on the pressure side. When working, the system pressure enters the inner cavity of the sealing ring through the small holes to achieve self-pressurization effect. It is suitable for sealing with a pressure higher than 7Mpa.

Material: InconelX-750, Inconel718
