NWP Split Groove Ductile Piston Rings (Pair) 50mm x 1.2mm

Replacement piston ring set from NWP. These piston rings are made from ductile cast iron, so your chances of breaking them during installation are greatly reduced. They also have a groove built around the middle, which results in less friction and heat transfer. The groove also helps retain lubrication. We recommend using a piston ring clamp set when changing piston rings. These rings are 50mm in diameter and 1.2mm thick.
