The Material -
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.
The Design -
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.
The Features -
- 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 of clogging.
- 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
- Scraper rings, when called for, use an expander ring under the scraper
to provide proper tension.
The deves line started in sweden about 1932, and was
manufactured by bildeve i stockholm ab - makers of precision car lifts,
industrial lifts and hydraulic elevators. The line quickly established
a reputation for quality and advanced design. In 1965, Janasz corporation,
with an international reputation in fine steels and precision machinery,
began importing the deves line into the united states. in 1976, Janasz
corporation purchased the deves factory, and brought the whole operation
to this country...lock, stock, and barrel. Also included was the secret
ingredient that makes Deves rings the finest in the world - Swedish Metallurgy.
Every step of the manufacturing process remains the same...every
cut, every mold, every quality control and inspection process. Production
personnel possess the same, if not higher, degree of skill and expertise
required by the Deves line. all this in a dedicated effort to maintain
the Deves reputation for quality, highest performance and outstanding
