Iglidur piston rings are economic, easy to install and are more wear resistant than PTFE-strips. They have a high load capacity and a wide dimensional range. They should be used when piston rings with excellent wear properties are required, when simple assembly is of great importance, when high edge loads occur or when tailor-made solutions based on iglidur materials are required. They cannot be used when the piston rings should also act as a seal or when different diameters should be managed by one part. The standard piston rings are made from iglidur J, while and the custom materials include iglidur A180, iglidur J350 and iglidur X.
