A kit of made in China "O" rings will be made to a low price not a high quality. Automotive and aeronautical stuff will be full spec in most cases, able to deal with wear, temperature, chemical attack and pressure etc. I would not trust a cheap selection box of "O" rings for anything critical. Perhaps some distributors will sell selections of different sizes guaranteed to be made to a higher standard, like R.S. perhaps. Do "O" rings have a British Standard?
