ABSTRACT:
A seal for the articulating ball joint of a vehicle exhaust system to prevent exhaust leakage. Vehicle exhaust systems include several connected sections to direct exhaust from the engine through the catalytic converter and out the tail pipe. At least one articulating ball joint is included to compensate for vibrational movement between the engine and the exhaust system. The joint seal of the present invention incorporate a bi-metal body with a first end secured to a portion of the clamp assembly and a second end which seals the gap between the members of the ball joint to prevent exhaust leakage therebetween.
