Perfect Circle Piston Rings
MAHLE, manufacturer of Perfect Circle® piston rings, is the largest manufacturer of piston rings in the world, leads the way in ring technology and innovation. Perfect Circle rings are at the forefront of both light and heavy vehicle piston ring technology.
Extensive OE connections mean that Perfect Circle rings have the technological edge. Innovations in Perfect Circle piston rings include the CP-20 oil ring, narrow compression rings, steel compression rings for gasoline engines, low tension oil rings and coated compression rings for diesel engines, all of which came from the OE. Now, MAHLE’s rededication to the Perfect Circle Piston Ring performance line proves that Perfect Circle should be the ring choice under every hood - regardless of the application.
Until recently, grey cast iron or ductile iron was the material of choice for automotive applications - today, steel is preferred over iron by more and more engine designers. Steel compression ring technology, pioneered by the former Perfect Circle group, has been used in heavy-duty applications for over 30 years. That know-how has become essential to the design and engineering of today's automotive engines. Mahle Piston rings for sale have come to be a beautiful addition to manu an engine, and Perfect Circle Piston rings by Mahle keep getting better with every new innovation.
Steel piston rings offer higher tensile strength, higher yield strength, greater fatigue life, and greater hardness while still offering a lower ring mass. These factors lead to better stress resistance, reduced groove pound-out, longer service life, better conformability, superior oil economy, and superior blow-by control while still lowering friction.
