Marine Exhaust Couplers and Fittings
Even the strongest boat exhaust systems can eventually suffer damage from heavy use. Our inboard exhaust connectors and fittings let you quickly repair a marine exhaust or design a custom layout to maximize efficiency, power and safety. Shop for dozens of exhaust coupler products made of resilient materials like powder-coated cast iron and rustproof fiberglass. We have 45- and 90-degree exhaust elbows, Y-fittings, return loops, tee reducers and other connectors. Straight exhaust pipes can be ordered by the foot in almost any diameter.
Marine Parts Source also has brass fittings for joining the pipes to the exhaust manifold, letting water circulate in wet exhaust systems. These include NPT barbs at straight and 90-degree angles. We carry the leading marine exhaust brands such as Centek, Barr Marine and Buck Algonquin for boat owners and professional technicians. Call us toll-free at 866-388-0390 Monday through Friday if you have questions about ordering boat exhaust adapters.
