O-Ring size specifications are varied, the usual national standard, American standard, Japanese standard and other standards, each standard diameter and outside diameter are different.
O-ring standards are mainly GB 1235-76, GB3452.1-92; Japanese standard P TYPE, G TYPE, S TYPE, SS/V TYPE, F TYPE; American standard AS568, British standard series; European standard series
There are two data components: d1-nominal inner diameter, d2-section diameter. d2-section diameter. There are also letters: A-1.80mm; B-2.65mm; C-3.55mm; D-5.30mm; E-7.00mm.
