Duraloy materials are specially formulated engineering plastics for use both as seals and as ancillary devices such as wear rings or high-pressure anti-extrusion rings. Duraloys possess the strength and wear properties needed to function under higher pressure and high temperatures, as well as low friction, and/or wider chemical resistance.

Important Note: Maximum/minimum temperatures and other operating limits listed on this website or otherwise provided by American High Performance Seals can vary greatly depending on seal configuration, media, operating temperatures, pressures, surface speed, dynamic running surface finish and working environment. Seals cannot be operated at their upper pressure, speed and/or temperature ratings at the same time. For longer seal life expectancy, do not operate your seal beyond 75% of any of its operating limits.
