OEM replacement loop-style exhaust muffler clamp for 1-1/2" outer diameter Cummins Onan RV generator exhaust pipe. Required for installation of the Onan 0155-2449 Exhaust Resonator. Includes clamp and mounting hardware. 90-day limited warranty.
The Cummins Onan 155-1015 is a genuine OEM loop-style exhaust muffler clamp for Cummins Onan RV generators. It secures exhaust system connections at 1-1/2" outer diameter pipe, preventing loosening from engine vibration, heat cycling, and road movement.
This clamp is the required installation hardware for the Onan 0155-2449 Exhaust Resonator — the resonator ships without a clamp, and part 155-1015 must be ordered separately to complete the installation. It is also a general-purpose replacement clamp for any Cummins Onan exhaust connection using 1-1/2" O.D. pipe.
See the yellow callout below for an important note on how this clamp is stamped and how to confirm the correct fit.
Clamps exhaust pipe with a 1-1/2" outer diameter — the standard size used across many Cummins Onan RV generator exhaust systems
Loop-style hanger clamp design provides a secure, low-profile connection around exhaust pipe without requiring additional brackets
Includes one (1) clamp and mounting hardware — complete for a standard installation with no additional fasteners needed
This is the OEM-specified clamp for installing the Cummins Onan 0155-2449 Exhaust Resonator, which is sold separately without a clamp
This clamp will be physically stamped or marked "1-3/8"" — this is the inner diameter (I.D.) of the tubing it clamps. However, per Cummins Onan drawings and technical documentation, the clamp is specified to fit 1-1/2" outer diameter (O.D.) pipe. The two measurements differ by 1/8". To summarize: • Pipe O.D. this clamp fits: 1-1/2" • Pipe I.D. this clamp fits: 1-3/8" • Stamped on the clamp: 1-3/8" If you are matching by the number stamped on your old clamp, a clamp marked "1-3/8"" is the correct replacement — that is this part.
• One (1) Loop-Style Exhaust Muffler Clamp • Mounting Hardware Complete hardware for a standard installation. The Onan 0155-2449 Exhaust Resonator requires one (1) of these clamps and is sold separately.
