This compact, on-the-job handbook provides all the practical and theoreticalinformation to design elastomeric O-ring seals for the full range of static,reciprocating, and rotary functions.Complete with fully illustrated, detailed examples to guide you step-bystepthrough virtually every seal design situation, Practical Seal Designprovides thorough coverage of ring seal geometry, material-compoundcapability, material performance, and design methods ... detailed designconsiderations including stretch, swell, shrinkage, and blowout prevention,as well as innovations to extend seal life span and minimize systemhysteresis ... unmatched treatment of piston-cylinder seal and shaft sealdesign ... and clearly elucidated specifications for military, aerospace, andindustrial standards.With quick-access features to facilitate prompt, proper, and effective design,Practical Seal Design is an essential single-source reference for mechanical,manufacturing, industrial, automotive, aeronautical, and ocean engineers.Furthermore, this one-of-a-kind work is an excellent reference text forprofessional seminars on hydrodynamic, pneumatic, and mechanicalengineering systems, and undergraduate mechanical design courses.
