Changan's knitted wire mesh flex-joint seals stop these leaks. Also applicable in static joints, they absorb dynamic movement in exhaust systems caused by simple operational functions like turning an engine on or braking hard. Exhaust components with rigid pipe connections are prone to leaks, increased noise and vibration and overall premature failure. Sandwiched between the inner and outer pipes, knitted mesh spacer rings allow a constant gap to be maintained even with thermal expansion caused by temperature changes within the exhaust system. Knitted mesh spacer rings also act as extremely effective vibration dampers, protecting exhaust components, due to the tiny springs that are formed by the looped wires created during the knitting process.
