ABSTRACT:
A reinforcement insert for use in a coupling components in marine exhaust systems. The insert is generally made of a much stronger material than fiberglass and is inserted within corresponding openings of exhaust system components which are to be coupled. Thereafter, a sleeve and pipe clamps are secured to the exhaust system components and tightened thereon. The inserts prevent fracturing of the coupling area between the exhaust system components and thereby prevent dangerous leakage conditions which could otherwise result in the sinking of a vessel or other undesirable consequences.
