There is a certain amount of interference compression between the O-ring and the groove; specific selection specifications are available and can be checked

If it is a Steckel seal with dimensions of 200*179*8.1, where the bore diameter is 200H9, the inner diameter of the groove is 179H9, and the width is 8.1; the corresponding O-ring size is 177.17*7； There are relevant standards; depending on the application of the O-ring (reciprocating, rotary, hydrostatic, etc.), different groove shape standards apply. It is recommended that you consult the relevant manuals
