@AdithyaR_YXE @amandalhu @DonateMask I don't think 9210 is rated for oils, but it's not rated for fluids (but has some mild fluid resistance anyway). I don't know why 9210 exists actually, but it generally seems better unless you really need fluid. Fit test from 1870/9205 transfers but not vice versa (9210 tighter),
@AdithyaR_YXE @amandalhu @DonateMask 我不认为 9210 适合油类，但它不适合流体（但无论如何都有一些轻微的流体阻力）。我不知道为什么 9210 实际上存在，但除非你真的需要液体，否则它通常看起来更好。适合 1870/9205 传输的测试，但反之亦然（9210 更紧），
