Genuine Cummins Onan 90-degree exhaust elbow for RV QG 5500/7000 generator exhaust systems. Replaces the standard 1-3/8" O.D. downtube and allows the tailpipe to be routed through the generator base opening. Compatible with Cummins Onan HGJAA and HGJAB generator models. Not for HGJAC models. 90-day limited warranty.
The Cummins Onan A026E097 is a genuine OEM exhaust elbow with mounting flange for the HGJAA (Marquis Platinum) RV QG 5500 EFI and RV QG 7000 EFI generator series. It connects the generator's internal muffler to the external exhaust tailpipe system via a 90-degree bend, directing exhaust gases away from the generator enclosure.
The elbow features a 1-3/8" pipe diameter and an integrated mounting flange for secure attachment to the generator's exhaust outlet. Using a genuine OEM elbow ensures the correct fit to the flange, proper exhaust flow, and compliance with Cummins Onan's emissions certification requirements.
