Piston Ring Oil Control

In 1956 we invented the multi piece oil ring followed by the flex vent expander the design standard by which all other oil rings are compared today.

Piston ring oil control.

The hastings oil control ring is energized by our flex vent expander which provides uniform pressure through two steel rails assuring positive oil control. Unlike the others the tension of the oil ring is controlled by the radial thickness of both of the oil rails as well as the size of the gap in the expander ring. It must not be fitted in grooves other than ones of the same section. They don t have to seal against the bottom land either since the oil ring is not a compression ring but rather a control mechanism that cools and lubricates the piston by collecting oil and distributing it evenly on the cylinder walls.

An oil control ring is fitted into the lower groove of the piston. It is an excellent motor ring or seal. Taper sided compression rings are utilised to control ring sticking problems in high output engines. They are available in single piece and spring energized configurations with a wide range of scraping land designs.

Generally the second and third compression ring are taper faced and supplied to improve oil sealing. The oil ring is also the primary stabilizing component of the ring pack. By manipulating the different. Oil control piston rings and seals are used in conjunction with other rings or as stand alone applications.

Oil control rings and seals are used in light vehicle gasoline engines and truck diesel engines. Hastings is the pioneer of oil control ring technology.
