The Nasen ring can take one of several forms - plain faced or taper faced, square cut or under cut depending on the attributes of the application.

Shortens running-in period and increases oil scraping ability of the ring.

When installed the ring twists itself, thus improving its oil control qualities

The natural working profile of a piston ring is a barrel face. By pre-profilling, the rings running-in period will be reduced and oil film forming chracterics optimised.

For increased oil scraping performance this type of ring offers increased wall pressure at the contact lands.

Slotted oil control rings remain the standard type of oil rings for many industrial application.

The most fundamental type of compression ring used for all forms of compressors, pumps and other applications.
