Piston rings and rider rings

■Piston ring
Fluorocarbon resin(PTFE) made rings are furnished in segmentel rings made of carbon filled plastic are supported by tension rings by using of outward tension of it to seal the gas.
A double-row configuration and the cut surface of each ring is set in a different position in order to enhance sealing effect and prolong service-life.
Both segmented carbon filled plastic made rings solid type fluorocarbon resin(PTFE) made rings are available. Both of them have a long service-life and particularly, since the solid type has a structure that is never affected by back-pressure, it can be used for a long period of time.

■The number and material of rings are selected carefully in consideration of several parameters such as gas composition , pressure , temperature , etc., by an excellent and experienced engineers.

■Various kinds of materials that are manufactured under an advanced quality control system are tested repeatedly for a long period of time. Only materials that are excellent in wear resistance are adopted. Moreover, they are designed with more than enough allowance. Therefore, they surely provide customer satisfaction in terms durability, performance and safety.
