What Does Briggs & Stratton 691031 Do?
The 691031 O-ring seals the dipstick tube on compatible Briggs & Stratton engines. The seal helps prevent engine oil from leaking around the dipstick-tube connection.
Because the seal is exposed to engine heat, oil and repeated service, it can eventually harden, flatten, crack or otherwise lose its ability to seal correctly.
What Does Briggs & Stratton 691031 Replace?
Briggs & Stratton 691031 replaces older part numbers 280393 and 270074.
Some older parts catalogs may also reference T280393. If the illustrated parts information for the engine supersedes one of those numbers to 691031, use the current 691031 replacement.
What Engines Use Briggs & Stratton 691031?
Briggs & Stratton 691031 is used across numerous small-engine applications rather than a single engine family. Verified examples include engine specifications such as:
- 122Q02-series engines
- 122K02-series engines
- 124T02-series engines
- 126T02-series engines
- 124782-series engines
- 282H07-series engines
- 15C114-series engines
- 104M0B-series engines
These are examples of documented applications, not a complete compatibility list. Fitment should always be verified using the exact engine Model, Type and Code.
691031 vs. Briggs & Stratton 691032
Briggs & Stratton lists 691031 as an O-Ring Seal and separately lists 691032 as a Dipstick Tube Seal. They are different service part numbers and should not be assumed to be interchangeable.
If the engine parts diagram shows both components, use the part number assigned to the exact seal location being serviced.
When Should the Dipstick Tube O-Ring Be Replaced?
Inspect the O-ring if oil is visible around the dipstick-tube connection or whenever the dipstick-tube assembly is removed for engine service.
Replace the seal if it is cut, cracked, flattened, hardened or otherwise damaged. An oil leak in this area can also have other causes, so inspect the dipstick tube and surrounding sealing surfaces before reassembly.
