Briggs Stratton 698401 Air Filter Retainer

Product Description

The BRIGGS STRATTON 698401 is a plastic air filter retainer designed to secure the air filter housing on small gasoline engines. This retainer holds the air filter element firmly in place, preventing unfiltered air from entering the carburetor during operation. It is a direct OEM-style replacement component used in routine air filter service and maintenance. At 0.18 pounds and measuring approximately 0.39 inches on each side, the part is compact but essential to maintaining proper air intake sealing. Technicians and small engine service pros install this part during scheduled air filter replacements or when the original retainer is lost or damaged.

This air filter retainer is suited for small gasoline engine applications where the original 698401 retainer requires replacement. Typical use cases include walk-behind mowers, outdoor power equipment, and other small engine platforms that use a compatible air filter housing assembly. Installation is straightforward and is commonly performed during standard air filter service intervals.

Installation Notes

Installation of this retainer is typically performed by small engine technicians during air filter service.

Remove the existing air filter and retainer, then seat the new retainer per the housing design before reinstalling the filter element. Ensure the retainer is fully secured before returning the engine to service.
