Carburetor-to-Insulator Seal
The STIHL 4792 149 0502 Gasket installs between the carburetor and insulator in the engine intake system.
A properly sealing gasket helps maintain the intended airflow through the carburetor and intake system. A damaged, deteriorated, or improperly seated gasket can allow unwanted air to enter the engine, potentially affecting engine performance.
Replacing the gasket during carburetor or intake-system service helps restore the proper sealing surface between these components.
Designed for STIHL RB 800 Pressure Washers
The 4792 149 0502 Gasket is designed for compatible STIHL RB 800 gas pressure washer applications.
The STIHL RB 800 is a heavy-duty pressure washer, and maintaining the engine's carburetor and intake components is important for dependable operation.
Because STIHL parts can sometimes vary depending on equipment production date or serial number, verify your model, serial number, and illustrated parts diagram before ordering to ensure proper fitment.
Ideal for Engine & Carburetor Maintenance
The 4792 149 0502 gasket is a practical replacement when the existing gasket has become:
-
Torn
-
Cracked
-
Hardened
-
Compressed
-
Damaged
-
Deteriorated
-
Leaking
-
Removed during carburetor service
-
Unable to provide a proper intake seal
It is generally a good practice to inspect sealing gaskets whenever carburetor or intake components are removed for service.
Installation & Maintenance
Before installing the gasket:
-
Turn off the pressure washer and allow the engine to cool completely.
-
Disconnect the spark plug or ignition system as appropriate.
-
Remove the required air-filter and carburetor components according to the applicable service procedure.
-
Remove the old carburetor-to-insulator gasket.
-
Carefully clean the mating surfaces without damaging them.
-
Inspect the carburetor, insulator, and mounting surfaces for damage.
-
Position the STIHL 4792 149 0502 Gasket correctly between the carburetor and insulator.
-
Reassemble the intake components according to STIHL specifications.
-
Make sure all connections and mounting hardware are properly secured.
