Rubber Piston Rings

Piston rings are subject to wear as they move up and down the cylinder bore due to their own inherent load and due to the gas load acting on the ring.

To minimize this they are made of wear resistant materials such as cast iron and steel and are coated or treated to enhance the wear resistance. Before we delve into materials the responsibilities of a piston ring must be reviewed.

For this reason the surface properties of the sealing surfaces are critical to proper seal performance. With strong alliances to specialty molding houses we can provide custom molded shapes and hard to find sizes and materials. The rubber piston ring should fit perfectly to avoid thermal throttle and severe damage to the engine. The moving piston rod generates high pressure on the piston seal which increases contact forces between the seal and cylinder surface.

As rings become thinner this heat transfer function becomes even more critical.

They are internal to the cylinder head and seal against the cylinder bore preventing fluid from flowing across the cylinder head. While sealing combustion pressure is the obvious goal an equally important function is to transfer heat from the piston to the cylinder wall. This allows pressure build up on one side of the piston making the cylinder extend or retract.
