Finest Swedish steel, from the masters in advanced metallurgy,
in a special composition alloy, designed for high heat
transfer, high flexibility and low wear rates. These
are characteristics yielding performance unmatched by
any other line of piston rings - American or Foreign.
DEVES rings and ring sets are based on detailed engineering
drawings as well as actual engines. They are manufactured
for almost all current American and Foreign engines,
with some model coverage as far back as 1928! All DEVES
rings are checked for fit by a specially-designed light-beam
microscope (if light doesn't get through, neither will
oil), and they meet or exceed SAE, DIN or BNA standards.
* All DEVES rings, compression, scraper, or oil control,
are made in the necessary lengths and widths, and in
various thickness' to ensure the proper tension against
the cylinder walls.
* Expander rings are slotted to prevent any possibility
* Oil rings consist of two laminated rings, which sit
at the top and bottom of the groove, separated by a
spacer, and also contact an expander ring.
* Scraper rings, when called for, use an expander ring
under the scraper to provide proper tension.
