Genuine OEM tailpipe hanger with flexible bracket and clamp for 1-1/2" O.D. Cummins Onan RV generator exhaust systems. 6-1/2" length. 1-year limited warranty.
The Cummins Onan 155-2174 is the OEM exhaust tailpipe hanger for Cummins Onan RV generators using the 1-1/2" outer diameter exhaust system — the QG 5500/6500/7000 (HGJAA, HGJAB, HGJAC) and Quiet Diesel QD Series families. It supports the tailpipe end and at intermediate points along longer runs, as required by the Onan installation manual.
The flexible bracket segment absorbs vibration between the tailpipe and the RV frame attachment point, reducing rigid stress on the pipe joints and fittings. The clamp is included — no separate hardware required for installation.
Built-in flexibility absorbs vibration and reduces rigid tailpipe stress at mounting points — extends the service life of pipe joints and fittings
Pipe clamp included in the kit — everything needed to mount the hanger to the tailpipe in a single purchase
Sized to provide adequate reach from the RV frame or floor structure down to the 1-1/2" O.D. tailpipe run below
Tested and designed specifically for RV generator exhaust applications — OEM parts maintain system integrity and preserve Cummins Onan warranty coverage
The 155-2174 fits 1-1/2" outer diameter exhaust pipe — the system used on QG 5500/7000 (HGJAA/HGJAB/HGJAC) and QD Series generators. Older Onan families including BGE, NHE, KV, and NH RV use a 1-1/4" O.D. exhaust system and require a different hanger. Confirm your generator's exhaust pipe diameter before ordering.
