Moving vertically to either the 70 or 90 durometer band, you will find the expected range of load in pounds per linear inch of O-ring. WebHow to Use the Gland Calculator. O-ring seal configurations are categorized as either axial or radial. Radial seals have squeeze applied to the inside and outside diameters and … WebTechnical Handbook O-rings Lower compression set values indicate improved remaining seal capacity. Compression set values generally increase with increased temperature and time. For O-rings the minimum squeeze should be about .007 inch. (0,175mm). The reason is that with a very light squeeze almost all elastomers quickly take 100% compression set. did david berkowitz have a mental condition
