Oil Control Ring

When it comes to oil control rings, Hastings is the innovator.
We invented the multi-piece oil ring followed up by the Flex-Vent® expander, the design standard by which all other
oil rings are compared.

• The Flex-Vent expander oil ring is energized by two steel rails, which receive uniform pressure from the expander to assure positive oil control. The three-piece design allows rails to be manufactured with a small cross-sectional area for better conformability to the bores of today’s low-tension, low-friction engines. The rails thin wall contact also allows for quick break-in time.
• Hastings rails are normally chrome plated to resist wear and extend engine life.
• Flex-Vent® rails are made of tough, wear resistant steel. The expanders are made of stainless steel.
