Static Joint Rings

Cobalt based with other super alloy grades available to seal in the most demanding areas of the turbocharger.

Static Joint Rings are the best solution for variable geometry nozzle sealing.

Our static joint rings are designed to seal the joint between the nozzle ring and housing for certain variable vane designs. They help minimise losses in the VGT system by sealing against lost pressure and bypass of the turbine wheel through to the exhaust outlet. The rings are able to cope with the stresses and strains that alter the shape of the turbo components at high temperatures, forcing more of the exhaust gases around the turbine wheel to produce a more efficient compressor system.

  • Proven in many existing applications, including high end turbochargers for passenger cars.
  • Made from cobalt-based super alloys and typically square in ring section.

  • Seal in the most demanding areas of the turbocharger.

  • 1.2″ (30mm) to 3.1″ (80mm) typical diameter range, other sizes can be accommodated.

Static joint rings can be used in any sector or industry, and we can assist with design development to help achieve a seal that is fully effective and reliable, yet cost controlled due to our manufacturing processes that minimise waste of the super alloy materials required to withstand harsh, high temperature environments.

As with all our other products we are very happy to adapt them to meet the needs of your application, choosing the right material to best suit the performance requirements.
