Cords duaflex - unique versatile design
CORDS Duaflex Piston Rings are highly effective in restoring performance to tired and worn engines. This is due to the unique design of CORDS Duaflex piston rings.
They are made to each piston manufacturers precise specification and can be used in both cast iron and aluminum cylinders. Each set consists of a number of segments, all there to perform a specific task and all capable of moving independently.
As a result, tapered bores are very efficiently sealed. At least one "cupped" segment is used in each piston groove to give the ring the vertical tension which seals the groove; the segments also tend to retain oil between them which cuts down wear by lubricating the cylinder walls upon startup.
piston ring sets and steel rings for special application
The ring sets contain multi segment steel rings and are manufactured for petrol and diesel engines (without the need to re-machine the piston) to restore the compression and oil control performance in re-built engines.
The steel rings conform to the tapered and oval condition in worn bores and each set is supplied with cast iron or steel top rings.
The ring sets are available to suit standard and over sized bored and most of the sets listed can be supplied from stock.
The CORDS Duaflex steel compression and oil control rings are equally suitable as Original Equipment for new engines, giving quality performance and long life.
