Briggs & Stratton Cylinder Head Gasket - 273280S

Product Details & Features

Ensure a tight and reliable seal at the top of your Briggs & Stratton engine with this genuine OEM cylinder head gasket (273280S) — a critical replacement component when servicing or rebuilding the top end of compatible small petrol engines.

This 273280S cylinder head gasket is precision‑manufactured to Briggs & Stratton’s exact specifications to fit between the engine block and cylinder head. It is crafted from a durable composite material engineered to withstand combustion pressure, heat cycling and vibration — helping to maintain proper compression and prevent oil and fuel leaks. It’s a direct, like‑for‑like replacement for original head gaskets and supersedes older numbers such as 273280 and 272614. 

Key Features:

• Genuine OEM Quality: Manufactured to strict Briggs & Stratton standards for accurate fit and dependable sealing performance. 

• Critical Engine Seal: Forms a robust combustion‑proof barrier between the cylinder head and engine block to help maintain engine compression and prevent oil or gas leakage. 

• Durable Construction: Made from high‑quality composite gasket material that resists heat, pressure and long‑term use. 

• Direct Replacement: Designed to replace original part numbers 273280S, 273280 and 272614 on many Briggs & Stratton single‑cylinder OHV engines. 

• Wide Compatibility: Commonly used on a range of 21 and 28 Series Briggs & Stratton OHV engines (including many 210702, 215807, 218807, 219907 and similar models) — ideal for lawnmowers, garden tractors, pressure washers and other outdoor machinery. 

Why It Matters:
The head gasket plays a vital role in the integrity of your engine’s top end. Over time, gaskets can degrade, leading to compression loss, overheating, poor performance or oil/fuel leakage. Replacing a worn or damaged head gasket with this 273280S unit helps restore proper sealing, supports efficient combustion and extends engine life — especially after head removal for valve work, decoking or other repairs. 

Ideal for top‑end rebuilds and routine maintenance, this genuine Briggs & Stratton head gasket helps keep your equipment performing reliably season after season.
