Daros Piston Rings designs and manufactures piston rings for a wide range of 2-stroke engines, from the most common engines used in the marine industry to major power plants. We can supply piston rings for all 2-stroke engines being produced today.

Chose a ring with the Daros Piston Rings name on it and you’ll be getting a ring based on expertise that has been gained over the period of more than a century. It also guarantees that they will meet the highest standards of today’s engine designs.

The various different piston rings being used in engines around the world all stem from a standard solution developed by engine makers and ring manufacturers; one based on tests and statistical data gathered over a long period of time.

There is a range of standard rings available for various different operating conditions. The ring’s unique properties come from choosing a combination of different materials, coatings, geometry and gap.

The features for a ring pack typically address different operating conditions such as:

• Standard ring pack provides a normal time between overhaul (TBO)


• Heavy-duty ring pack ensures Long Time Between Overhaul and high scuffing resistance.


• Quick running-in ring pack provides a fast sealing, reducing time to full load.


• Ring groove wear resistant ring pack ensures prolonged lifetime for the piston crown grooves.

In more severe conditions in the combustion chamber, the need for various combinations will increase and Daros can provide a unique solution to address the required performance.
