ASTM D1414 Rubber O-Rings: Rubber Swell of O-Rings

O-Rings are elastomer loops used in pumps, valves and other mechanical components to seal lubricant-elastomer interfaces.   Lubricants that come in contact with O-rings may cause them to either shrink or swell, depending upon the chemical nature of the components in both.  While a small amount of swelling enhances the O-rings ability to seal the system, excessive swelling or softening may result in leakage.  Like-wise, shrinkage (a negative swell) may defeat the purpose of the O-ring entirely. This test determines the amount an O-ring swells or shrinks from lubricant exposure.  

Elastomer properties of interest are determined; the elastomer is placed in the lubricant for the test time at the test temperature.  The properties are again determined and the percent swell, + or -, and change in hardness are reported.
