LAHDEK 2pc 35mm x 1.2mm Piston Rings

SKU CH-3BY6-X6QHT

Two 35 mm by 1.2 mm piston rings for two-stroke petrol chainsaws, trimmers, brush cutters and mowers

  • Two rings per pack for convenient spares
  • 35 mm bore fits many 2-stroke engines
  • 2 mm thickness matches original specs
  • Petrol-powered tool compatibility across saws and trimmers
  • Direct replacement part restores compression fast

Direct-Fit Replacement

These two piston rings measure 35mm in diameter and 1.2mm thick, matching the original specifications for a wide range of two-stroke petrol engines. They are designed for owners and repair shops servicing chainsaws, trimmers, brush cutters and mowers that require this exact size.

Simple Installation

The rings install into the piston groove without special tools, restoring compression in worn cylinders. Each pack contains two rings, providing a spare or allowing both grooves to be serviced at once. No gaskets, pins or circlips are included, so existing hardware must be reused or sourced separately.

Durable Under Heat

The steel construction resists the high temperatures and friction of continuous two-stroke operation. Proper ring tension maintains a consistent seal during extended cutting sessions, preventing power loss and hard starting caused by blow-by. Regular inspection ensures the rings remain free in their grooves for reliable performance.

Questions about this item

How does the 1.2 mm ring thickness affect engine compression over time?

The 1.2 mm thickness maintains the seal between piston and cylinder wall; wear reduces compression until the ring end gap exceeds service limits.

What happens to the 35 mm rings when the two-stroke engine runs hot all day?

Thermal expansion closes the end gap; if clearance is insufficient the rings can bind, scuff the bore or lose tension.

Which existing engine parts must match the 35 mm bore and 1.2 mm groove for these rings to fit?

The cylinder bore must measure 35 mm and the piston groove width 1.2 mm; the piston, cylinder and wrist pin must already be in serviceable condition.
