   • Damps vibration between the connected exhaust components.

3. Durability:

   • Withstands high temperatures and pressures produced by the diesel-powered PF6 engine.
   • Resilient to wear and corrosion from prolonged exposure to exhaust gases.

Material:

• High-Temperature Metal:
  • Typically constructed from stainless steel or heat-resistant alloys.
• Composite Layer:
  • May feature a graphite gasket or ceramic coating for enhanced sealing and resistance to thermal stress.

Application in Nissan PF6 Engine:

1. Engine Type:
   • The PF6 engine is a six-cylinder diesel engine used in medium to heavy-duty Nissan trucks and buses.
