Description
Overview:
The Briggs & Stratton Gasket-Exhaust (part number 820817) is a genuine OEM sealing gasket for the exhaust outlet on small petrol engines. It sits between the cylinder head and the muffler or exhaust manifold to create a gas-tight joint. Made from heat-resistant gasket material suitable for high temperatures and vibration, it helps prevent exhaust leaks, fumes, and soot escape. This supports correct back pressure and smooth running, protecting nearby parts from hot gas blow-by. Suitable for a wide range of Briggs & Stratton powered machinery such as lawn mowers, garden tractors, generators, pressure washers, and compact construction tools, it is a straightforward replacement during routine servicing or when refitting the exhaust. Being a genuine Briggs & Stratton part ensures correct fit and dependable performance.
