When This Part Needs Replacement

Replace this joint if the threads are corroded, seized, cracked, leaking, heavily scaled, or damaged during exhaust elbow removal. It should also be inspected whenever the mixing elbow assembly is serviced.

Installation Notes

Parts Desk Insight

This part lives in a harsh exhaust/water mixing environment, so corrosion is common. When replacing the joint, it is smart to inspect the full mixing elbow assembly at the same time instead of treating the connector as an isolated failure.
