What Does Briggs & Stratton 806425 Do?
The 806425 exhaust gasket provides a seal at the engine's exhaust connection. Depending on the specific engine and exhaust configuration, the gasket is positioned at the exhaust flange where the cylinder-head exhaust outlet connects to the exhaust manifold, pipe or muffler assembly.
The gasket helps keep exhaust gases contained within the exhaust system rather than allowing gases to escape around the mounting flange.
What Briggs & Stratton Engines Use 806425?
Briggs & Stratton lists 806425 for various engines rather than a single universal application. Official illustrated parts lists document the gasket on several larger engine configurations.
Examples include select engines in families such as:
- 385446 engine specifications
- 385777 engine specifications
- 386447 engine specifications
- 386777 engine specifications
- Additional compatible 38-series Briggs & Stratton engines
These are engine-family examples, not a guarantee that every specification within those families uses 806425.
Do not order 806425 based solely on engine displacement, horsepower or equipment brand. Briggs engine service parts should be matched using the complete Model, Type and Code.
Do I Need One or Two 806425 Exhaust Gaskets?
The required quantity depends on the engine and exhaust configuration. Many compatible Briggs & Stratton V-Twin engines have two separate cylinder exhaust outlets and use two 806425 exhaust gaskets.
For example, Briggs illustrated parts documentation for certain 38-series engines specifies quantity 2 for reference number 883, part number 806425.
Because 806425 is typically sold as an individual gasket, check your engine's parts diagram before ordering quantity.
806425 vs. Other Briggs & Stratton Exhaust Gaskets
Briggs & Stratton produces several exhaust-gasket designs. Part numbers that may appear similar in a catalog are not automatically interchangeable.
For example, Briggs documentation can specify 806425 for certain 38-series configurations while other engine families use exhaust gaskets such as 690970, 691613 or other application-specific part numbers.
Match the gasket by engine parts diagram rather than by appearance.
Is Briggs & Stratton 806425 the Same as 690970?
No. Briggs & Stratton 806425 and 690970 are different exhaust-gasket part numbers used on different engine configurations.
Do not substitute one for the other unless the parts documentation for the exact engine specifically identifies a supersession or replacement.
When Should the Exhaust Gasket Be Replaced?
Inspect the exhaust gasket when the exhaust manifold, pipe or muffler assembly is removed. Replacement is appropriate when the existing gasket is burned, damaged, crushed, torn or no longer capable of sealing the exhaust connection.
Signs of an exhaust-system sealing problem can include visible exhaust leakage or soot around the exhaust flange. Noise or leakage can also be caused by loose hardware, damaged exhaust flanges, cracked exhaust components or other problems, so inspect the complete connection.
How to Confirm Briggs & Stratton 806425 Fitment
Locate the engine identification information and record the complete Model, Type and Code.
Use those numbers to find the Briggs & Stratton illustrated parts list for the exact engine. Look in the exhaust or engine-gasket section and confirm that the exhaust gasket is listed as part number 806425.
