Description
Overview:
This is a genuine Husqvarna piston ring for 362XP and 372XP chainsaws, supplied to OEM specification for a precise fit and dependable sealing. Built from durable, heat- and wear‐resistant metal suitable for high‐temperature two‐stroke operation, it restores and maintains cylinder compression so your saw starts reliably and runs smoothly under load. Correct sealing reduces blow‐by, helping the engine deliver stable performance during felling, limbing and general cutting. Dimensions for reference: outer diameter 52.6 mm (2.07 inches); ring gap 6.6 mm (0.26 inches). Identified by OEM No. 503 28 90-42 and MPN 503289042, this ring is a direct replacement for a worn or damaged part and is an ideal choice during a top‐end service or routine maintenance on Husqvarna professional saws.
Key Features:
- Genuine Husqvarna part for assured compatibility and durability
- Maintains correct compression for easier starting and consistent power delivery
- Precision-made to OEM tolerances for an accurate seal in the cylinder

- Supplied to spec: OD 52.6 mm (2.07 inches), ring gap 6.6 mm (0.26 inches)
- Direct replacement to resolve loss of compression or hard starting
- Straightforward to fit during piston and cylinder servicing (refer to workshop manual)
- Suitable for regular maintenance schedules for trade, forestry and domestic users
Typical Applications:
