DESIGN DATA FOR 0-RINGS AND SIMILAR ELASTIC SEALS. Period covered: June 1, 1957 to December 31, 1957
A study to gain knowledge of design dnta for O-rings and similar elastomeric seals is continued. The literature survey on O-rings and seal design has been continued and enlarged to include the effects of irradiation and extreme low temperature on seal design. Low temperature tests, relaxation and volume change tests, screening tests, and functional tests have been conducted. The functional tests include pulsed annulus tests with various groove configurations and reciprocating shaft tests with and without different types of back-ups at room temperature and at elevated temperatures. No over-all relationship between physical property values and seal efficiency has been found. It has been noted, however, that certain physical properties appear to be important to seal life for specific seal conditions. (auth)
