Mahle is the world's largest manufacturer of piston rings. Their tremendous research and development and extensive OE connections mean that Mahle Original standard piston ring sets have the technological edge. Things like narrow compression rings, steel compression rings for gasoline engines, low-tension oil rings, and coated compression rings for diesels all came from OE. Mahle's entire Original line proves time and again that it should be the ring of choice under every hood - regardless of the application.

Mahle Original standard piston rings offer high tensile strength, high yield strength, and excellent hardness with low ring mass. These factors lead to stress resistance, minimal groove pound-out, long service life, cylinder conformability, oil economy, and good blow-by control with low friction. Whether you're repairing a modern computer-controlled engine, or rebuilding an older engine, be sure to specify Mahle Original standard piston ring sets (formerly Perfect Circle) … trusted by professional automotive technicians for over 100 years.
