Description
A piston ring is a circular metal ring with a beveled edge located at the top of the piston, responsible for sealing the combustion chamber and preventing gas from leaking into the crankcase. It is usually made of high-strength material designed to withstand pressure and temperature changes, and it controls the flow of oil around the piston.
Features
- Piston rings have a nitrided surface treatment for added wear resistance.
- Specially manufactured to ensure proper fit by matching piston and cylinder dimensions.
Applications
Piston rings act as a seal between the piston and the cylinder wall.
