Static Joint Seals

Bespoke sealing solutions to improve the performance and efficiency of your turbo compressor system.

Specialist Variable Geometry Turbocharger Nozzle Seals

Static joint rings are the best solution for Variable Geometry Turbocharger (VGT) nozzle seals in high performance turbocharger systems. These rings are specifically designed to seal the joint between the turbocharger nozzle rings and the housing in certain variable vane designs.

They play a critical role in minimising energy losses within the VGT system by preventing pressure leakage and bypass of the turbine wheel. This results in more efficient redirection of exhaust gases through the turbine, boosting overall system performance.

Our rings are built to withstand high temperature distortions and mechanical stress, ensuring reliable performance even in the most demanding environments.

Proven, Durable and Efficient

Used in many existing applications, including high end turbochargers for passenger cars, our turbocharger nozzle rings are:

  • Made from cobalt-based superalloys and typically square in ring section
  • Capable of sealing effectively in extreme temperature and pressure conditions
  • Offered in a typical diameter range of 1.2″ (30mm) to 3.1″ (80mm) – with other sizes available

Why Choose Cross?

At Cross, we understand the unique demands of turbocharger nozzle rings and variable geometry turbo systems. That’s why we tailor our solutions using the most suitable materials and advanced manufacturing processes, and we can assist with the design development to help achieve a seal that is fully effective and reliable.

Our process is designed not only for reliability and performance, but also to reduce minimal waste, especially when working with high value superallys. This helps to keep costs under control without sacrificing quality.

VGT Nozzle Seals FAQs

Are these seals suitable for passenger and commercial vehicles?

Yes. Our static joint rings and VGT nozzle seals are proven in a wide range of turbocharger applications, from high end passenger cars to commercial vehicle platforms.

VGT nozzle seals help maintain precise exhaust flow by preventing gas leakage around the vanes. This results in better turbine response, improved boost control, and overall enhanced engine performance.

Absolutely. Our rings are designed to maintain sealing integrity even under high thermal loads and component distortion – conditions typically found in Variable Geometry Turbocharger nozzle seals.
