CPN Ring Set for One Piston
CPN
Gas Nitrided Steel 1.0mm Top Ring
Taper Hook Groove Napier 1.2mm 2nd Ring
2.8mm Flex Vent Oil Ring
Top Ring
The top ring is a steel compression ring that has been gas nitride so that it is compatible with Nikasil and cast iron bores. This scuff resistant gas nitrided ring allows it to operate at maximum efficiency without blemishing up the bore. The nitriding ensures extended life and protection under extreme conditions.
Second Ring
The second ring is a cast iron with a taper underhook groove face. The THG ring acts as a wiper and pushes the oil back away from combustion. This type of ring allows you to run a lower tension oil ring.
Oil Ring
The oil ring is made up of two soft nitride rails with a low-tension expander. Because of the miniflex vent design;there is less friction on the cylinder wall, which increases the performance and efficiency of the engine. These ring sets are high strength and low tension, resulting in maximum sealing with minimum drag.
