When it comes to piston rings, many of the world’s most recognizable and trusted brands come to us, including Chrysler, General Motors, Harley-Davidson, Ingersoll-Rand, Emerson, MTD, and many other Tier One manufacturers. But we’re trusted for more than our product offering. The difference is also in our innovative designs, responsive service, competitive prices, high order-fill rate, and on-time delivery.
Rectangular type has no ID bevel. Sometimes seen in internal combustion engines, it is widely used in compressors and pumps.
This common top ring profile has a convex face, enabling a higher ring face contact pressure, and can be symmetric or asymmetric. This profile results in improved combustion gas sealing and improved oil control versus a straight-faced ring. Coatings include: Plasma Moly, Chrome Manganese Phosphate, or Ceramic PVD.
This ring type is trusted for increased gas side sealing and better oil control. It may have barrel or straight face. Coatings include: Manganese Phosphate, Chrome and Plasma Moly.
Primarily used in diesel applications, the Full/Half Keystone type prevents carbon build up and ring sticking. It also creates additional surface area for side load bearing. Coatings include: Chrome, Ceramic Chrome, and PVD.
This twist ring creates an OD bottom side scraping edge that helps wipe oil off the cylinder wall and into the crankcase. Its sharp edge contact helps speed break-in.
This reverse twist ring along with a taper-machined ring face duplicates the OD bottom side scraping edge of a positive twist torsional ring. Reverse twist promotes side sealing that prevents oil from being forced under and behind the ring resulting in better oil economy—a very common second ring profile in modern gas engines.

The Flex-Vent oil ring is the benchmark for oil control ring price/performance. Its three-piece design allows rails to be manufactured with a small cross sectional area for better conformability to bore – even with today’s low-tension, low-friction designs.
Although this design is not as conformable to the cylinder wall as three-piece designs, its rigid cast iron or steel body provides the durable axial structure required to function long term in compression fired diesel engines.
Two-piece spring designs are made for improved tension and better conformability. However, it will not unitize in specific engine design applications or in applications that require severe extended running times. Used in some diesels engines, vintage applications, and compressors, this style is available chrome-plated for long service life.
The one-piece design makes for ease of installation and simplicity. It’s available chrome-plated for long service life. The style is used in some diesels engines, vintage applications, and compressors.
