33 mm 2-Stroke Piston Ring Pair

This replacement set includes two piston rings sized 33 mm by 1.5 mm for small petrol-powered garden equipment. It fits a range of chainsaw, hedge trimmer and strimmer engines that use this exact bore and radial width.

Single-Ring Groove Compatibility Limit

Each ring is designed for a single piston groove; engines requiring multiple rings per piston or a different cross-section will not seal correctly. The 1.5 mm radial width also determines the maximum allowable groove depth, so wider or narrower grooves are incompatible.

Verify Bore and Groove Dimensions Before Ordering

Measure the cylinder bore and the piston groove width on your existing engine to confirm they match the 33 mm diameter and 1.5 mm thickness. Also check that the engine is a 2-stroke petrol type, as 4-stroke or diesel units use different ring profiles.

Questions about this item

Should I choose the 33mm or 1.5mm version for my engine?

This set uses a single specification: the ring has a 33mm bore diameter and a 1.5mm axial width, so there is no alternative version to select.

What does the 33mm bore size mean once the ring is installed in the cylinder?

It matches a cylinder with a 33mm internal diameter, allowing the ring to seal the combustion chamber and control oil on the piston wall.

Is there a specific installation standard for the 1.5mm width that caps the end-gap or orientation?

The 1.5mm width fits the piston groove depth; end-gap and orientation follow the engine manufacturer's service manual for that model.
