Description

Overview:
This Genuine Husqvarna piston ring is a direct replacement for selected two‐stroke engines used in Husqvarna disc cutters and chainsaws, including the K950 and 394XP. Built from durable, heat‐resistant steel for long service life, it seals the gap between the piston and cylinder wall to maintain correct compression. Reliable compression is essential for easy starting, clean combustion, consistent power, and efficient fuel use. The ring is manufactured to OEM tolerances to match the original fit and performance of your machine, helping to restore output after wear. It is suitable for routine top‐end maintenance or a full rebuild when addressing loss of power, high blow‐by, or increased fuel consumption on demanding cutting and forestry tasks.

Key Features:
- Genuine Husqvarna part for assured compatibility and performance
- Maintains cylinder compression for strong starting and steady power
- Durable steel construction for heat, load, and wear resistance in tough use
- Precision fit to OEM tolerances for reliable sealing and reduced blow‐by
- Helps improve throttle response, cutting speed, and overall efficiency
- Supports cleaner running by promoting proper combustion
- Suitable for routine maintenance or top‐end rebuilds after wear or scoring
- Straightforward to fit for trained users with standard workshop tools
- Designed for Husqvarna K950 series cutters and the 394XP chainsaw
- Replaces worn rings to extend engine life and protect the cylinder

Typical Applications:
Replacement during scheduled maintenance or engine rebuilds on Husqvarna K950 disc cutters used for concrete, masonry, and metal cutting, and on the 394XP chainsaw in heavy‐duty forestry work. Ideal when restoring compression after hours of use, heat‐related wear, or piston scoring, and when addressing symptoms such as difficult starting, low power, or excessive exhaust smoke.

Also known as:
Piston compression ring, cylinder compression ring, engine ring, top ring. Commonly referenced as the piston sealing ring for the cylinder and piston assembly in two‐stroke engines.
