The primary usage of the piston ring is to seal the chamber (where the piston is moving), which can be a combustion chamber of a 2-stroke or a 4-stroke engine. Marine engines have three or more types of rings fitted on the circumference of the piston.
The piston ring is an essential piston part, and its numbers and functionality differ depending on the type and capacity of the engine.
We offer a wide range of high-performance piston rings designed for your most demanding engine applications including diesel engines. If you need NT855 engine piston ring, welcome to contact us.
The oil control ring is installed in one of the carrier's outer grooves. When installing the two-part oil control ring, be sure to pay attention to the position of the helical expander. The end of the helical expander must always be opposite the ring joint.
