The Multiquip HS52010458R Cylinder Gasket HS-81A is a genuine OEM replacement designed for the HS-81A handheld saw. Sourced directly from Multiquip, this gasket delivers the exact material grade and dimensional tolerancing required by the HS-81A engine assembly. Genuine OEM designation means it matches the original component specification without substitution or compromise. If you're servicing an HS-81A and need a cylinder gasket you can count on, HS52010458R is the correct part.
Key Features
- OEM-Grade Sealing Material — Manufactured to the original compression and heat-resistance specification required by the HS-81A cylinder, ensuring a proper combustion seal from the first start.
- Drop-In Cylinder Fit — Engineered to the exact bore profile and bolt-pattern of the HS-81A cylinder deck, seating flush without trimming or rework.
- Confirmed HS-81A Fitment — Part number HS52010458R is verified for the Multiquip HS-81A handheld saw; always confirm your model before ordering.
- Maintains Combustion Integrity — A correctly installed cylinder gasket sustains proper compression and prevents exhaust blow-by that causes power loss and hard starting.
- Fuel and Exhaust Safety — A failed or improperly spec'd cylinder gasket can allow combustion gases to escape at the cylinder joint; using the correct OEM gasket eliminates that risk.
The cylinder gasket seals the joint between the cylinder and the engine crankcase or head, containing combustion pressure and preventing gas and oil from escaping the engine. On a two-stroke handheld saw engine like the HS-81A, this seal is critical to maintaining the compression ratio the engine needs to run cleanly and deliver full cutting power. When a cylinder gasket fails — whether through heat cycling, improper torque, or age — the engine loses compression, becomes difficult to start, runs rough, and may overheat due to escaping gases disrupting the combustion cycle.
