Briggs & Stratton Cylinder Head Gasket - 698717

Product Details & Features

Ensure your Briggs & Stratton engine runs with proper compression and no leaks with this genuine OEM cylinder head gasket (698717). This essential engine seal sits between the cylinder head and engine block, creating a tight, gas- and oil-resistant barrier that helps maintain optimal combustion and performance. 

The 698717 head gasket is designed to meet factory standards for fit, durability and sealing performance on a wide range of Briggs & Stratton vertical shaft engines — particularly 09 and 10 Series models used in walk-behind lawnmowers, pressure washers, tillers and other outdoor power equipment. Its reinforced composite construction with a metal fire ring around the cylinder bore ensures a reliable seal under heat and pressure, helping prevent compression loss, exhaust blow-by and oil leakage. 

Key Features:

• Genuine OEM Quality: Built to original Briggs & Stratton specifications for precise fit and reliable sealing. 

• Critical Engine Seal: Forms a gas-tight and oil-resistant seal between the cylinder head and engine block to maintain proper compression. 

• Reinforced Design: Composite material with a metal fire ring resists combustion heat and pressure, helping extend engine life.

• Wide Compatibility: Suitable for many vertical shaft Briggs & Stratton engines where part 698717 (and superseded numbers like 272536S, 272170, 270341 and 692288) are specified. 

• Straightforward Replacement: Installed when servicing the top end of the engine (e.g., after decoke, valve work or head removal) to restore proper sealing and operation. 

Why It Matters:
A compromised head gasket can lead to poor starts, loss of power, overheating, white smoke or oil leaks. Replacing it with this genuine 698717 part helps restore engine compression and combustion integrity — essential for smooth, dependable engine performance season after season.
