Cat® 115.54 mm OD Ductile Iron Exhaust Coupling for Engine Air Lines
Description
The exhaust coupling used in turbochargers is a specialized component that connects the turbocharger housing to the engine exhaust manifold or midsection. It is typically made of metal and is cylindrical, with a diameter that matches the exhaust pipe it connects to. The coupling provides a secure, leak-free connection between two sections of exhaust pipe.
Features
- Withstands the extreme temperatures and pressures that can occur during operation
- Resists corrosion, wear, and chemical activity
Applications
The exhaust coupling is used at the inlet and outlet to connect the exhaust outlet to the muffler or other components, and absorbs vibration and movement caused by engine operation.
