A piston ring is an expandable split ring used to provide a seal between the piston and the cylinder wall. Piston rings are commonbly made from cast iron. Due to the new sulphur cap 2020 regulations MAN B&W have introduced cermet coated piston rings. For older types or engines that use for example scrubbers and keep running on HFO we have types such as aluminium, bronze and ceramic coated versions. 

Other options are piston rings with gas tight lock and left-hand, right-hand executions and models with different dimensions such as 9, 11, 12,5 and 14 mm.
