Parts Desk Insights

Best use case: This straight 2-1/2″ adapter is the right call when a customers exhaust or drain hose exits directly off the valve or manifold without needing to turn common on larger inboard diesel installations where the exhaust run has enough room to go straight to the through-hull. Its the straight companion to the 2-1/2″ 90 elbow; the key question to ask is whether the hose exits straight or at an angle. At this price point, customers are making a deliberate purchase for a specific installation always confirm pipe thread size (2-1/2″ NPT), hose ID, and whether straight or elbow is needed before ordering. Bronze is the correct material for wet exhaust and raw water applications due to its combined heat and corrosion resistance.
