LAHDEK 10pcs Piston Ring Kit 35mm x 1.2mm

Piston Ring Kit for 35 mm Bore

This kit supplies ten piston rings sized at 35 mm diameter by 1.2 mm thickness for small petrol engines. It suits trimmers, brush cutters and chainsaws that use a matching bore and groove. The parts are new and intended as direct replacements during a rebuild. Both two-stroke and four-stroke applications are covered by the same dimensions.

Dimensional Limits of the 35 mm x 1.2 mm Standard

The rings only seal correctly when the cylinder bore measures 35 mm and the piston groove accepts a 1.2 mm radial width. Wear beyond the manufacturer's tolerance or a different bore size will prevent proper compression. No oversize or alternative thicknesses are included in this pack. Verify the exact measurements before disassembly.

Straightforward Press Fit With Common Pitfalls

Installation requires expanding each ring just enough to slide over the piston into its groove without twisting or snapping the metal. The most frequent errors are over-expanding the ring, fitting it upside down or confusing the top and second groove positions. Clean the grooves thoroughly and follow the engine manual for ring orientation and end-gap staggering.
