The Honda 64186-ZB6-000 Muffler Duct Insulator B (Upper) is a genuine OEM component designed for EX2200 generators. As a direct Honda OEM part, it is manufactured to the same standards as the original, ensuring a correct, drop-in fit with no guesswork. Confirm your generator's serial number against the fitment table before ordering to make sure this is the right variant for your unit.
Key Features
- Genuine OEM Heat Management — sourced directly from Honda, this insulator is engineered to manage heat transfer within the muffler duct assembly, protecting surrounding components from exhaust-generated heat buildup.
- Exact OEM Replacement — manufactured to original Honda specifications, this part replaces the upper insulator position in the muffler duct assembly with no modification required.
- EX2200 Generator Fitment — designed specifically for the EX2200 generator; verify your serial number against the fitment table to confirm this is the correct upper insulator for your unit.
The Muffler Duct Insulator B (Upper) sits within the muffler duct assembly on the EX2200 generator, acting as a thermal barrier that reduces heat transfer from the exhaust duct to adjacent housing and body panels. This protects surrounding components from prolonged heat exposure that could cause premature wear or damage. When this insulator deteriorates or is missing, nearby parts are left exposed to elevated temperatures that can shorten their service life.
