DHS Equipment supplies this part to help keep your power cutter running at full capacity.
Key Features
- OEM Compression Tolerance — manufactured to Husqvarna's exact ring gap and radial thickness specifications, ensuring the sealing performance the engine was designed around
- Direct Cylinder Match — sized to drop into the original piston groove without modification, maintaining the correct ring-to-bore interface for proper seating
- Fits 3122K, K1250, and K1260 Power Cutters — confirmed fitment across these Husqvarna handheld power cutter models; verify with part number 503289026 and your machine's parts diagram
- Restored Engine Output — a worn or broken piston ring causes compression loss, increased blow-by, and reduced cutting power; this genuine replacement restores the combustion seal and brings the engine back to rated performance
- Fuel System Integrity — correct ring sealing prevents unburned fuel from reaching the crankcase, protecting the two-stroke oil film and reducing the risk of internal engine wear
The piston ring seals the gap between the piston and the cylinder wall, maintaining the compression needed for efficient combustion in a two-stroke engine. Without a tight seal, combustion gases escape past the piston, robbing the engine of power and causing hard-starting or rough running. Over time, a worn ring accelerates cylinder wall wear and can allow oil contamination into the combustion chamber — so replacing a damaged or worn piston ring promptly is one of the most effective ways to restore an engine to full working condition.
