The dimensions and tolerances of ring diameters and cross sections of Kalrez® O-rings on this list are as listed. All other quality aspects are in accordance with MIL-STD-413C of 8 Dec 1980, "Visual Inspection Guide for Rubber O-rings," except for white O-rings (compound 1045). O-rings made from compounds other than 4079, 1050, 1045, 1018, and 3018 may not conform to the dimensions shown due to differing shrinkage rates.
