The butt joint version of the piston ring is the standard type. This is most common in combustion engines with compression-, nose- and slotted oil scraper rings.

Euroring butt joint / Type A

 When designing a seal, it is important that there is sufficient amount of flexibility in terms of use. We also call this the final clearance or closed gap space (S1). The piston ring will expand/become longer by introducing heat to, for example, an internal combustion engine. The ring-ends come together but must not touch under any circumstances. If this occurs, the ring will ‘set’ itself on the cylinder wall and/or in the groove. The ring will jam and then deform. The result may cause the piston to jam, resulting in a blockage.
