Specifications

Automotive Exhaust Connectors (Bellows) with outer braid and with Inner Braid Hose provided on the inner diameter
These types have an internal sleeve of stainless steel wire braiding.
These types of Exhaust Connectors are used where the temperature and the noise levels are more than usual. The noise can be caused by the engine characteristics, and air flows over the bellows. The internal sleeve braid reduces the noise and dissipates the heat. Incases, where there is an excessive movement caused by the wear and tear, the internal braid sleeve prevents the over extension of the bellow. A braid lined Exhaust Connector is used where the typical temperature of exhaust is upto 800ºC. 
1) Automobile exhaust system component
2) Installed between engine and muffler
3) Used to decrease engine noise and vibration
4) Absorbs muffler pipe thermal expansion and shock
5) Compensates for exhaust converter misalignment
6) Reduces air pollution
