Bellow With Inner Braid

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.
