Parts Characteristics
J0503-0230-02 is the CUMMINS Onan exhaust hose with a 127 mm internal diameter, reinforced with the original stainless steel spiral wire so the hose keeps its round bore under the exhaust pulse and heat. The material is rated for the exhaust temperature of the generator set, and the ends are finished for the standard clamp arrangement. The hose is supplied in the original length for the exhaust route.
Applicable Models & Applications
This hose is used on Cummins Onan generator exhaust systems where the original J0503-0230-02 size applies, including the flexible sections between the engine exhaust outlet and the silencer or the ducting. Confirm the internal diameter and the length against the hose removed from your set before ordering. We can confirm the correct hose for your generator model from the exhaust layout.
Maintenance & Replacement
Inspect the exhaust hose at each service for cracks, soft spots and for corrosion on the spiral wire, which indicate heat or flexing damage. When replacing, fit the hose with new clamps and align it without sharp bends, and check the clearance from hot surfaces and moving parts. Re-check the clamps after the first heat cycle, as the hose settles with temperature.
